From Walnut Creek to Alameda, San Ramon to Livermore and beyond, we love selling and installing all types of ProVia doors. Most people are unaware of how a new door can greatly enhance the overall beauty of their home while simultaneously ensuring their protection and security. There may be no such thing as the perfect door, but there's certainly a perfect door for you, and Custom Exteriors can help you find it!
Siding not only impacts how the exterior of your home looks; it can actually contribute to its overall safety, stability, and comfort. Considered part of your house's "building envelope, " the siding acts as the physical barrier that separates the inside and outside areas of your home through seemingly disparate elements like insulation, foundation, and flooring.

Custom Exteriors is very responsive and they have excellent follow through. I called them because a neighbor used them a year or so ago and highly recommended them. We had an in home visit with David Lopez within three days of the call which was made on the weekend! David was an excellent rep, he took the time to listen and explain the products and the process they follow from order to finished installation.

The brand he showed us was the best we had seen so far in terms of quality and features we wanted. We were asking for new construction so it involved removal of trim, removal of old window, new window prep, install and finally install of trim with a wood based resin impregnated product and sealing to paint ready. When we got the bid, it was substantially more than we expected and twice what our neighbor had paid. David explained the reasons and even provided a sample showing what the neighbors home would have been priced at if done today.

I also did some industry research and found that David had explained the reasons for the increases accurately. Many economic factors created a situation that is driving prices up to levels not seen. Covid, remodeling demand, glass prices, supply chain issues, general inflation and cost of labor. In the end we decided to wait out the perfect storm in the hopes that prices may go down in the future.

It is a gamble that we decided to take based on our financial situation. Will it pan out? Only time will tell but when we are ready, we will go back to David and Custom Exteriors to get the work done. During this process we did not feel pressured at any point. Their honesty, integrity is clearly evident and they do offer a great product at a fair price, it was just not the right time for us. Thank you David and Thank you Custom Exteriors!

Replacing all the windows and 3 large sliders in my older home could have had lots of glitches and surprises but my installation with Custom Exteriors out of Pleasanton was such a great experience. Dave Lopez, sales manager, was low key, and very confident of his product and crew. He did a thorough job of showing me the quality of the product and explaining their outstanding warranties.

A really great surprise was the install crew. Outstanding team. Each knew their specific aspect of the job, and when there were questions, they made sure to let me know and make sure I was happy with the final product. The tech with least seniority it turns out, has been with the company for over 18 years. That speaks volumes. They managed the project like clock work. Bottom line: Big job, great crew, very happy client. Marcel C

The owner and his staff are very professional and helpful in each stage of the project. I am very happy with their workmanship. I just have a little complaint that between each step of the project, I had to wait so long and had to call them to ask when they could start the next step.

4-windows and 2-slinding glass doors installed. Rob Vigil started the process and was an EXCELLENT representative. Very patient, knowledgeable, and down-to-earth. THANKS Rob! The install team were GREAT! Their attention to detail was awesome. The next project is James Hardie siding. If this goes as well as the window experience, I'll be just as pleased. I HIGHLY recommend Custom Exteriors.

Custom Exteriors installed three windows for me. They were not only the best quote, there work was also top notch. I've had a bit of work done to my house during the pandemic and I always use these guys as my "gold standard"

We contacted Custom Exteriors and they responded within hours to our request. David Lopez visited our home and did a walkthrough and gave extremely detailed information about options, safety requirements, energy efficiency and more. It was a fantastic experience and we really felt like David and the Custom Exteriors team valued our home like it was one of their own.

I was looking for a sliding glass door with a built in doggie door. Custom Exteriors was the only place I could find that had these. They were very responsive in getting the door measured and making sure they understood my needs. No high pressure sales, no trying to sell me extra windows, and no "special deal" good for just that day (unlike another company). Door was just put in and everything went well. I'm very happy with it. I'll definitely return here for my future window or door needs.

Grayeagle came out he was extremely helpful in showing us all the products, explaining them in great detail, better assisting us with making our Window purchase and choice. He then explained all of the finishes and options we could purchase. Installation was exceptional the four-man team did the job in two days which was amazing, did a very awesome job, everything looks beautiful! I would highly recommend!

We had them over to provide an estimate to replace several windows. Very quick to give us an estimate that was higher than anyone else's estimate. The brand they proposed is on the higher end and I asked the consultant to help me compare it with another brand I've gotten an estimate for. After a week of follow-ups over email the answer I got was: "We don't carry the other brand.

Maybe go to Home Depot and see for yourself. If you are looking for the least expensive, I wish you luck". Two weeks of my time was wasted and what I got was an unprofessional answer.

Had a great experience upgrading my windows with Custom Exteriors. Tanner came out and provided me with a competitive quote and was a proactive communicator throughout the process. Unfortunately the windows themselves were delayed due to supply chain issues impacting everyone right now, so I had to wait a few months from time of contract to installation.

Once ready though, the installation crew came out exactly on time and completed the project of window replacement on 4 windows in a few hours. They were respectful of the property, efficient, and we are very happy with the quality of the windows. No more drafts and they look great too.

Can't say enough food things about this company. I was really impressed with the sales manager David Lopez, that came out in the evening and took time to explain all of our options.

Old original windows at the back and side of the house needed to be replaced, for they were almost seventy years old. Three were new construction and two were retrofit bathroom windows. The beginning of the process was professional and responsive to be fair. However, the middle and end of the entire contract was a nightmare. Experienced two anxiety attacks and the project lasted an extra four weeks as well as an extra two thousand dollars with last minute calls to an electrician and plumber with no help from custom exteriors, when they should have knowledge on water and electrical lines that run under or next to the windows they replace.

I have been given false information and omissions on what needed to be done on my end. I have been told different things from five different people from the company that did not add up and left me scrambling to fix, adjust, and coordinate last minute while I was at work. The technician who did the two bathroom windows did not handle the area with care.

When asked to fix the damages that was done from the installation, it was difficult to negotiate, like pulling teeth without anesthesia. I had plans to replace the remaining three windows at the front of the house in two or three years. Nonetheless, after this experience from a diamond certified company claiming 25yrs of excellent service and experience, I will not.

I choose this company after vetting seven other window contractors. I am disheartened. I would recommend to whomever read this to consider them with caution and one or two simple window replacements, not half or the entire house. I rarely write reviews, but this is a precedent.

Custom Exteriors installed Anlin windows and doors in my 40 year old condo replacing the rattling single panes that existed. The Anlin sound package has significantly reduced the noise from the Rossmoor Parkway. The crew's installation was flawless. Kudos for Custom Exteriors.

20 years ago we installed all windows and doors In our home. About 3 months I noticed a serious problem with installation of one patio door and window. I called Custom Exterior and Ryan came out to inspect. They redid the installation including some stucco work. Very outstanding service. Above and beyond. Thank you custom Exterior. Can not ask for a better contractor.

We had Custom Exteriors come out to replace the last 4 single pane windows in our home. They did a great job installing. The only thing that was a little annoying was that they did not paint the trim of two windows. I ended up having to paint them. Not too bad until I realized they used off white caulking. Which does not match the white caulking used around all of my other windows. Using an off white has created the two tone color effect around the windows. I'll now have to spend more time later to fix this. Wish this type of work was included in th quote.

Custom Exteriors replaced my old, leaky, single-pane windows & patio door with new Anlin windows & patio door. Their pricing was competitive, the windows arrived exactly when promised (10 weeks from order date), and the installation crew arrived on time and did an excellent job installing everything.

Custom Exterior was the most reasonable estimate we got when we decided to replace 19 windows and patio door. Our experience from the first contact to installation was smooth and easy. We were given an accurate estimate as to when the windows would arrive and amount of time to install. The installation team were professional, efficient and clean. Many thanks to Gray Eagle, Michael, and Roberto & assistant!

We have used Custom Exteriors on many occasions over the years. We are in Lafayette and love that they service this area. We think the work is fantastic, both for windows and doors. We had Anlin sliding doors (2) and a back door installed in May 2021. We had a question about how the doors were locking and the next day the owner himself (Jeff) made a personal appearance and solved all our issues in about 10 minutes! Talk about customer service! We look forward to using Custom Exteriors for many years into the future.

We do not trust this company anymore. We ordered the door on Dec 18th 2020, also prepaid 60% of the door. Unfortunately, they keep changing their delivery date! Now, they said the door can be delivered on April 29th. But still not guaranteed. I understand why now. They don't manufacture the doors, they are just a middle man. This information was never disclosed by their salesman. We are extremely disappointed at their service. March, 17th, the owner called me today, said he will help to push up the delivery date. I appreciate his help.

We had a wonderful experience with Custom Exteriors! Jeff (the owner) was so professional and was very attentive to all of the details of our job. Grayeagle handled all of the online specifics of our order. Whenever we had any questions or changes he responded very quickly. All in all we felt very taken care of by Custom Exteriors and most importantly our windows are beautiful. We couldn't be happier. If you want a great company that is professional and values their clients, use Custom Exteriors. You won't be disappointed.

I am so happy i found Custom Exteriors. I had a referral from a neighbor after i was shocked to see the first bid i received for all new windows. Robert came over and customized my whole house plan and let me know what he recommended. We had new construction and replacements and each window turned out fantastic. The owner also stopped by before the installation and let us know he thought under our old aluminum siding was real siding and he would remove it if we wanted.

After the first window, we found out he was right and they tore off all the old 1970 siding for us. Our crew, led by Roberto, and then Salvador on stucco was outstanding. I cant recommend this company enough for fair pricing, cleanliness, attention to detail and timeliness! Thank you Custom Exteriors for our new windows.

We went with Custom Exteriors because they are Diamond Certified, but we were impressed with what they had to offer. They are not the cheapest, but I would say mid-range for what we were looking for. It was hard for us to find a window contractor because the last window contractor we almost worked with, was about to lose his license and was trying to get us to work with him anyway. Luckily, no money was lost or work was done, but finding a contractor we could trust was a challenge.

Depending on what you do, the order takes 6-8 weeks, more like 8 for us. When they do schedule, they do show up on time. I'm just relieved to get 1967 windows and doors out of our house. The only thing we noticed was glue residue on the outside. Other than that, everything looks great.

I live at Rossmoor, a community with over 6,000 condos. Rossmoor has very strict HOA rules and all work must comply with Rossmoor's code, which exceeds City requirements. As seen in the attached photos, my townhome required custom built windows. I received 3 estimates, one estimate was several thousand dollars over Custom Exteriors estimate, another was similar but that company had much less experience in Rossmoor.

Custom Exteriors' estimate included all work and there were no surprises. The job went perfectly as promised. On day one the original windows were removed and new windows were installed. On day two their stucco crew applied new stucco and wood trim. On day three their painter completed all of the painting. Custome Exteriors facilitated the inspections throughout the process.

The company has a long history and very good relationship with both the City of Walnut Creek building department and Rossmoor's alteration's department. The permit process went very smoothly. It pays to go with a company that is known and respected by the City of Walnut Creek and Rossmoor's alterations department. The bottom line is that working with Custom Exteriors was a great experience and I highly recommend them.
