We had a great salesperson come to our home and measure for a door. After leaving and submitting an invoice with only a stock door (so we could decide on style and color), the problems began. We emailed the office contact we were given multiple times to obtain color and hardware information. When we did get a response, it was unclear the options and inconsistent information was given.
We were frustrated, so we gave up for a couple weeks. When we tried to reengage, we were told they are no longer doing doors. This is inconsistent with their website and phone system. The contact also said they had followed up with us - not true. We're unsure if they are not telling the truth to avoid the work or that they were caught not servicing customers.

First it took many calls and emails and follow ups to get an appt. Keystone cops internally as is how it appeared. When their "technician" finally came out he was more interested in random chit chat then talking about the project. After a few weeks they finally got back to us and said they weren't interested in the job. It was small : two doors and two custom windows plus installation. Some years ago this seemed like a very different company. Very disappointed

Yikes. It's disheartening to hear the experience that my husband had with this company; more specifically, the interaction that was had with one of the owners, Ron. In short, he was belittling and lacked professionalism in his course of action when handling a customer's request. It's definitely surprising to see this coming from the leadership team at JB Sash and Door. Overall, great products. Just be mindful that your requests and/or concerns may not be valued.

JB Sash were supposed to replace 9 windows in my apartment. The day of the installment they realized, even after two early measurements, that one of the windows was the wrong size. They realized that only after they have already removed my old window and had to reinstall again the old one in a very precarious way. I had to wait more that 6 weeks before having them coming again with the new window.
And then what happened? They took the measurement wrong again and came with a wrong window again! I thought this was a joke, doing twice the same mistake without any consideration. I have been waiting now more than 3 months to have all windows replaced. Not a good service. If you have alternatives I would suggest to go somewhere else.

About 10 years ago ordered about $30K of Marvin windows through them with removable grills (biggest mistake ever). They have never fit. They finally had to send someone out to custom make them. They are now starting to fall out again.and shatter. JB Sash will not support. Very disappointing. Won't go to them again.

Dealt with them on quite a few occasions. They have been around for a long time, I first dealt with them in the 80's. They're all attitude and they think they're the guarders of windows and doors. In specialized situations they're difficult to navigate through. When you have to come back to address an issue, they don't want to hear about it. Their pricing is high. Projects I've used them on for doors, I've spent hours and hours describing how to manufacture these doors to go into openings.
I felt like I should have been there to order the doors myself. My customers I've sent there in the past have all came back frustrated. They said they seem like they didn't want the business.

Called today to ask if they install basement doors. The lady on the phone said yes and let me transfer you to our sales team. I told the sales rep what I was looking for and he told me that I'm better off finding a handyman or one man contractor. They don't come out to price and install one door. All we need is a solid basement door in a custom size ordered and installed. What was I thinking calling a window and door place for a door?

I have called this company about 3 times over the last 5 years trying to get quotes on doors. My latest call was yesterday, and the woman I spoke to, and I wish I could remember her name, couldn't have been more dismissive to what I was looking for. She seemed more interested in steering me away from requesting a quote than actually wanting my business.
She basically told me that she had a lot of other larger orders and didn't know when she could get to my smaller request. She was trying to beat around the bust about it, which was even more annoying. Had she been upfront and said "hey, we have a lot of orders ahead of you, it might take X amount of days to get this ordered", I would have actually respected that more, at least it would have been honest. I despise companies that behave like this, and will certainly not be calling them again in the future.

JB Sash and Door won the contract for our building because the local historical society picked their window as the most accurate looking. This decision has caused pain for all the unit owners in our building, I'll give you my pain - First a minor gripe. The windows suck. The mechanism for supporting the open window breaks and they become useless.
I arranged to have mine repaired and they are repairing several others around the building because they are failing at a high rate (at my expense of course, but I'd guess they are out of warranty, so fine) Here's the major gripe. First, I had to prepay the full amount. Then I had to schedule a technician to come in months in advance. Finally the magic day arrived, and the tech worked on the window for 3 hours while I sat in the next room quietly working. Then, I came out for lunch and the tech is just gone.
I check my window? Now it doesn't open at all. After a few phone calls and emails it is determined that one of the two mechanisms brought to repair the window was defective. They will order a replacement and fix it at no charge to me (good). I ask to reschedule and I hear nothing. Finally the super in my building who is coordinating the repairs across the building tells me they will come two weeks hence (which is today), at 1:30. 1:30 rolls around, nothing.
At 3pm I call, email any means of contact. The tech calls me back and says he's not sure if they have the part and they may need to reschedule. Honestly, I totally understand that, but WHY DIDN'T I GET A CALL YESTERDAY. OR TODAY. OR NOT UNTIL I CALLED THEM, 2 HOURS PAST THE WINDOW THEY WERE SUPPOSED TO ARRIVE? I had to make special arrangements with work to be home today, and I disrupted my whole kitchen to give the tech easy access, as well as arranging my family to be out of the house to reduce everyone's COVID risk.
So right now, I don't know if or when they will actually make this right. I understand almost all of the problems, what I don't understand is the lack of communication. I'm annoyed as a customer and a resident, and frankly I am drafting a letter to our historical society to ask them to reconsider using this company in the future.

Don't waste your time. Like other reviewers, we had someone come to the house to measure and discuss different products (up to 6-7 windows in all). We were told we'd receive a quote within 5-6 days. That was almost one month ago. After several attempts (calls, texts) to get the quote, we've decided to move on, as this is not a good sign of future service and responsiveness. With this type of "customer service" I'm really not sure how they stay in business.

Worked with Quinn at JB Sash to get quotes on over 20 windows we planned for our remodeled house. Very cooperative, and knowledgeable of the windows we were looking for. Went trough many iterations, in terms of size, models, and figuring out final configuration to meet our pricing needs as well. Excellent customer service from Quinn. We will definitely go back to JB Sash for any future needs!

JB door and Sash replaced my windows in Back Bay and it has been life changing! They did an amazing job. Handled the landmarks commission approval, matched the interior and exterior paint colors, and the installation was a breeze. They put down plastic to cover my floors and furniture, and cleaned up after themselves, you would never know they were there.
I actually threw a party 4 hours after they left and I did not need to clean up after them at all! Essentially all communication via email, and easy to communicate with. They took my apartment to a breezy, apartment that mirrored the outside temperature, to nearly sound-proof. Windows look amazing! Highly recommend.

We went to JB Sash because of their reputation. We needed a new front door and had them measure and provide an estimate. These folks are professional and are excellent craftsmen. They were great on follow up and scheduling and the door was installed perfectly and looks fantastic. In fact, the storm door that was already there, had to be removed and reinstalled.
It fits better than before! In the past, I used one of those radio window, door, roofing companies and will never waste my time or money on them again. Disaster! The right people to go to (right now) is JB Sash & Door. We couldn't be happier with the results or the price.

DO NOT USE! We are building a new home and placed an order for all of our doors and windows over 8 months ago with JB Sash & Door. We are still missing doors, components required for built in Marvin shades and some shades never arrived. Several of the custom door orders had to be re-done. Very disappointed at a time when we should be so excited.

About 13 years, I replaced over 20 windows with Double Hung Wood framed JB Sash windows, LOTS OF MONEY. I say a little over 2 years ago the windows started to have this condensation in the top sash on over half of the replaced windows. I was battling a medical condition and finally got around to having JB Sash come out last fall to look at the windows.
I was told the glass is defective. It took well over six months to get the quote. JB Sash wants to charge me the cost of replacement glass plus labor on each window. OH ya, they discontinued this window so they are saying it is not covered under warranty. Hmmm, the GLASS is defective - the glass should have warranty. Now, some of the windows, the bottom sash glass is showing signs of the defective glass. Very FRUSTRATED! Poor service, awful windows ---

We had our front door replaced by JB Sash. The work was done quickly, was affordable and the quality was great. I was on the fence originally about replacing the old door but after seeing the new door, I'm very happy I did! I wish they could have painted it before install but that isn't a huge deal. Very happy!

Came and measured - never followed up or priced out. After several attempts made, I never get a call back. Called the office (who wanted to help) and finally sent over an estimate of the wrong products. what a waste of time and energy. Your reviews will surely catch up with your "75 years of being in business."

I called this company because we were looking for a subcontractor for a project we were awarded, once they picked up the phone I introduced myself and proceed to explain my reason for calling, which was to follow up with a previous email sent requesting an estimate. The lady that picked up my phone didn't even listen to what I was saying and said, "we are not interested". not interested in giving a quality costumer service i guess.
As a client, one of the things we appreciate is honestly and great service. The only thing I can say about this company is they lack professionalism. I imagine all the business this company has lost because of the receptionist. called place on 1/4/2019 at 11:42 am

We had a very positive experience with JB Sash and Door. Everybody who works for them is so friendly and helpful. From our first telephone contact and subsequent emails to make arrangements, we felt comfortable and appreciated. Then Dennis came out to discuss options with us and take measurements. He was very professional and pleasant to work with.
The men who do the installations for the company are wonderful people. The window we had put in was very, very large, so it took a day-and-a-half for them to complete the project. We did not mind having them around at all! Before we decided to go with JB Sash and Door, we got several estimates which were all about the same. Certainly not cheap, but we have confidence in the product, and in the future will be happy to do business with JB Sash and Door.

So I go in to inquire about 6 loft size windows. The two individuals at the desk continue talking as though I am disturbing them. The woman finally allows me to interrupt to describe how my windows don't work correctly. She asks me who the manufacturer is and I said I didn't know since the building is old. The gentleman told me they sell windows and do not repair them.
I said that was fine because I didn't know if they needed repair or replacement. He suggested I hire a handyman; that is genius. Why didn't I think of that and went to a window and door vendor instead. My advice? Go somewhere else or find a handy man LOL.

We did a very large window project, and JB Sash was great to work with. Windows are expensive, and that stinks. But Cheryl and the team at JB Sash handled everything, without any headaches. We had them out for an estimate and information session, then got a quote, and nailed the project down. A few weeks later, the installers came and handled everything with aplomb.
Within a few days, we were (almost) all set.* Jason and Mark both deserve special mention for their expertise, but Ben and Eddie working with them were also friendly and skilled. I've little doubt that everyone JB Sash hires is both well-trained and personable. Following this purchase, I may not need to deal with installing windows again, if I'm lucky. However, I can certainly recommend JB Sash to others! * We had one hiccup, but it was well handled. 1 window out of 33 was incorrectly sized, and needed to be re-ordered.
I don't know if that window got screwed up by a typo when ordering, or the factory messed up the fabrication, but it was never our problem to deal with. JB Sash handled replacing it, and a few weeks later, our final window was installed, and the project done.

I have about 20 JB Sash windows in my house. Every year one or two of the balances breaks. (See other reviews.) Called ten times, left polite messages, and can't get anyone to call me back. Cheap product and utterly unresponsive! Update: Got a call back, finally, the same day I posted the review. Looking forward to the fix!

I have to commend Cheryl and her staff at JB Sash. I replaced all my windows in my back bay condo in Boston from across the country in California with the help and professionalism of Cheryl. I did not even get to see the out come of their work until 4 months after installation. I have to say, I was very pleased with the 6 windows that were replaced.
The windows had to be custom ordered and built, approved by the Boston historical society and the condo association. This process, however, did take 4 months for the simpler windows and 6 months for the bay window. Quality and craftsmanship are superb. Windows open smoothly and the double panes cut the city noise outside significantly. The installers are neat and non obtrusive according to the tenants. I am very happy with their work. Thank you!

Went to the store to set up a home appointment, but their system was down, left information expecting to be called next day. Finally got called on Tuesday the following week. The salesman came to our house the very next day (Wednesday). This was just before tax free weekend. We were promised quote so we could place order over the weekend. Kept checking all week for the email quote.
It never came, being upset waited until Tuesday to call to inquire what happened. Response was OH, you didn't get it. Got quote the very next day, with minimal information (with no breakdown of the price), with no apology or mention of the matter. Nothing to compensate a little for the issue. Made us feel they could care less about our business. Funny thing was that the salesman came to our house, spent over an hour and could not have been nicer? Find it hard to do business with that kind of place.

I bought a door, a storm door and two windows from these guys. The first storm was smaller than the door (hello salesman) and returned it for a restocking fee. The door is nice but the salesman pushed a cheaper stock door on me, instead of what I ordered, I should have waited. The window guy they recommended to install was a total freak, the second day he actually brought his child (10?) to help, and asked my newly divorced brother if he had found God.
After a year I needed a part and had to bully the salesman to UPS it to me. Not as bad as Dorchester Door And Window, but close. I think if you are a contractor who deals with them a lot they are fine, but the average homeowner cannot expect too much. These guys really are in the replacement window business.

Some 16 years ago or so, I decided to replace the windows in my very old house, bought in 1995 and built sometime before 1916. Well, that was a doof move, I came to find out. "Always fix old windows, " said smarter people than me after it was too late because I already made the doof move. "They''re better and sturdier and" blah blah blah reasons for why my move, as I said, was a doof move.
Be that as it may, the doof move included buying replacement windows from JB Sash. Lots of windows. LIke, many thousands of dollars worth of windows. About 30, maybe. Big house. I still have the brochure for the windows I bought. It's nice and glossy. Features cut-aways to show you the high-tech channels your insulated window panes fit into. "Patent pending, " the glossy brochure crows. Flash forward 16 years, and these utter crap windows have busted side balances--not surprising, given how flimsy the plastic channels are on these I'm-so-great-I-need-a-patent windows.
That means it's a struggle to push them up, and then you have to quickly jam something in the opening to keep them up, or they'll make jam out of your hands. Such a great window to have when you rent to a family with toddlers, wouldn't you say? No, I didn't think so either. Beyond the finger/small child-eating broken balance smash-things aspect, there's also the WTF plastic channel at the top that has warped so you can't, actually, push the upper window half into it. There's a nice, inch-wide gap open to the outside on some of the windows, thanks to this.
Like fresh air? Like bats? Like bugs? Boy, does JB Sash have the replacement windows for you! Patent pending! Anyway, I'm working with Greg, the windows expert from Boston Building Materials Co-op. He's helping, doing a little research on repairing the windows, as opposed to replacing them outright, the idea of which hurts me because I'm poor.
So Greg writes to JB Sash, to find out about replacement parts for these windows, which, as I might have mentioned, cost me a F LOAD OF CASH lo these 16 years ago. This is the response he got from JB Sash, in entirety, about their super duper patent pending windows: "These windows & parts are no longer available. An all wood version is available but has no adjustable sill insert" Yes, that's right, JB Sash is so busy crafting expensive, Patent! Pending! windows, apparently, that they couldn't afford the time to put a piece of punctuation at the end of their 2nd sentence. Would that punctuation were their most egregious failing.
