Window ReplacementS Built for PA & NJ Homes
Professional Window installation & Replacement
Drafty, cracked, or outdated windows can cause higher energy bills, reduced comfort, and lost curb appeal. That’s why Dexteriors Roofing & Siding offers professional Window Replacement in Montgomery County PA. Our high-performance windows enhance energy efficiency, brighten interiors, and improve security while boosting your home’s overall value. Whether you need a few replacements or a full-home upgrade, our team ensures precise installation and stunning results.
Replacement windows are one of the highest-return home improvement investments. The right windows reduce energy bills by 25–30% in older homes, eliminate drafts, reduce outside noise, and modernize your home’s appearance. The wrong windows — or improperly installed windows — cause condensation, air leaks, and disappointment.
Dexteriors is an authorized ProVia dealer. We’ve chosen ProVia specifically because they build every window and door to order at their Ohio factory. There’s no off-the-shelf inventory — every piece is custom-built for your specific opening and your specific style preferences. That custom-build approach is why authorized ProVia dealers are selective: the installation has to match the build quality.
For our service area, we install primarily three ProVia lines: Endure (premium vinyl with fusion-welded frames), Aspect (vinyl with wood-grain interior finish options), and Signet (premium fiberglass for the most demanding installations). Every install includes proper flashing, professional interior protection, debris removal, and our 10-year craftsmanship guarantee.
What's Included in Every Installation?
- Custom-built ProVia windows specified to your home
- Removal and disposal of existing windows
- Proper flashing and weatherproofing at each opening
- Interior protection during installation
- Quality insulation around frame perimeters
- Exterior caulking matched to siding or trim
- Final interior trim work (if included in scope)
- Operation demonstration on every window
- Cleanup of all installation debris and packaging
- Permit handling and township coordination
- Manufacturer warranty registration
- Lifetime Craftsmanship Guarantee
Our 4-step Process
- Window replacement is detail-oriented work where the installation matters as much as the product.
- Free in-home consultation. We measure every opening, document the existing window condition, and walk through your priorities — energy efficiency, sound reduction, aesthetics, ease of operation. We discuss frame materials, glass packages, hardware, and color options.
- Detailed itemized proposal. You receive a quote with line-item pricing per window, full material specifications, and photos of similar past installations. We include factory data sheets for the specific windows you’re considering.
- Custom factory build and direct shipment. Your order goes to the ProVia factory, where each window is built to your spec. Typical lead time is 4–6 weeks from order to install date. We coordinate the install schedule around your availability.
- Professional installation. Our crew protects your interior with drop cloths and plastic, removes existing windows carefully, installs new windows level and square with proper flashing, and seals everything for long-term performance. Most full-house installations complete in 1–2 days.
- Final walkthrough and warranty activation. We verify every window operates smoothly, demonstrate proper operation if you have new locking mechanisms, register your manufacturer warranty, and activate your 10-year craftsmanship guarantee.

EXCELLENT Based on 50 reviews Posted on Miguel Perez (mikepe111)Trustindex verifies that the original source of the review is Google. Dexteriors is amazing. Last year, Dexteriors built us a huge covered deck, with lights, ceiling fan and stairs to the backyard in about 1 month. They also replaced our old door to the backyard with a sliding door. We used them again this year to screen the deck to reduce the amount of bugs there. The price was very reasonable compared to the other 3 quotes we got from other places. Communication with the team is fantastic, they made the whole process very straight forward. Scheduling is easy and once they start building, THEY BUILD. Thanks to Matt, Rick and the rest of the Dexteriors Team! We will use you again for future projects!Posted on Greg NardiTrustindex verifies that the original source of the review is Google. This is the Second time I have used Dexteriors…..2024 I had them restore my Rear deck which was really in bad shape…. The used the good sound structure and reinforced with more footings and made this look like a Brand New deck. Now 2 years later I was so Impressed with their PREVIOUS WORK I CONTRACTED THE TO DO my ROOF/Gutters and Fascia…….not only their quality work, they treated me like a FREIND….. Brothers: KEVIN AND MATT …..GO WAY BEYOND TO MAKE SURE YOU ARE HAPPY NO MATTER WHAT ALL THROUGH THE PROCESS AND BEYOND. Just received a complimentary card to reserve a 1 year inspection. I am extremely picky when it comes to contractors as I have done extensive remodeling and was a Maintenance tech for over 40 years, So when I encounter A TOP QUALITY CONTRACTOR, I stay with them. If you have them come out you will see for yourself. YOU WILL NOT REGRET CONTRACTING THEM!!!!Posted on Lisa CooperTrustindex verifies that the original source of the review is Google. We had Dexteriors replace our roof, siding, gutters, and some windows. We are so Impressed by the way our home looks! It was a truly amazing experience! We had met with 5 different roofing companies before we selected Dexteriors. Dexteriors stood out above all of them. From our first meeting with Kevin Gilmore, we were impressed. He was so informative and thorough. The entire team was super professional and did impeccable work. The team worked from sun up til sun down. Their attentiveness to every detail was impressive. Kevin and Matt Gilmore were so patient and guided us through all of the decisions that needed to be made for our project. Kevin, Matt and their team have a very impressive work ethic. We could not be happier with the results of our project. Dexteriors was great!Posted on Amy S.Trustindex verifies that the original source of the review is Google. So happy we chose Dexteriors! We had a few companies come out and give us estimates and ideas. Honestly, I was put off by some of the other companies that came out (and I'd say we are pretty easy to please). Other companies were very pushy and didn't seem to listen to what me any my husband were envisioning. Then Dexteriors came out. Happy with them the first day we spoke to them, during the build, and after! They listened, they offered ideas based on our budget, had great communication through the whole process, very friendly workers, keep a tidy work space, and do BEAUTIFUL, HIGH QUALITY WORK with ATTENTION TO DETAIL. Thank you Dexteriors for building our wonderful deck!!! Just a couple of pictures attached. They constructed the trex deck, railings, two gates, two staircases, added/extended roof to go over it, installed gutters, installed a sliding glass door, added lights/fan and outdoor outlets. The pictures do not reflect how beautiful it is in person!Posted on ED CALTERTrustindex verifies that the original source of the review is Google. Matt & his crew at Dexteriors did a phenomenal job removing our two tier deck and replaced with Trex. We will definitely be using them for future projects.Posted on Andrea JohnsonTrustindex verifies that the original source of the review is Google. We couldn’t be happier with our experience working with Dexteriors. Before choosing a contractor, we interviewed multiple companies, and Dexteriors stood out immediately. Their quote was fair, clearly explained, and gave us confidence right from the start. Thank you to Kevin Gilmore for our first meeting and for making such a great impression, he represented the company beautifully. We hired Dexteriors to build a roof over our patio and a custom media wall using materials that I specifically chose, even though they weren’t the easiest to work with. Despite that, the team handled everything with skill and professionalism, and the craftsmanship shows in every detail. Thank you to Rick Michael for the excellent communication and for doing such an outstanding job. A special thank you to our project manager, Matt Gilmore, who was absolutely excellent. He was highly responsive throughout the entire project, and whenever I had a question or concern, he addressed it quickly and thoroughly. His communication and attentiveness truly instilled confidence and made the entire process smooth and stress-free. The crew worked incredibly hard, showed up consistently, and maintained a high level of professionalism from start to finish. We are thrilled with the final result and genuinely so glad we chose Dexteriors for this project. Highly recommend!Posted on Shelby LeightTrustindex verifies that the original source of the review is Google. Dexteriors Roofing and Siding are fantastic to work with! They are clear in their communication ( often not the case with contractors) and they got our job done within the promised time frame they said they would. Again another rarity in the industry. Would definitely recommend you contact Dexteriors for any and all of your exterior home needs!Posted on Adam WeinraubTrustindex verifies that the original source of the review is Google. Matt and his team at Dexteriors is excellent. Originally met Matt to do my primary bathroom and kitchen which we are absolutely in love with. We then hired him to replace all of the windows in our house. He did an excellent job there as well. Not only does he do great work, he does it at a fair price and won’t cut corners or stop till the job is done right. I could not recommend matt and Dexteriors morePosted on David RTrustindex verifies that the original source of the review is Google. We couldn’t be happier with our experience with Dexteriors! They replaced our deck and installed a rain escape system, and from start to finish they went above and beyond. The crew’s attention to detail was outstanding, and they made sure every part of the project was perfect before wrapping up. Their professionalism, workmanship, and genuine care for customer satisfaction truly set them apart. We highly recommend Dexteriors to anyone looking for quality work done right!Posted on Tom TraubertTrustindex verifies that the original source of the review is Google. After a tree took out our existing deck, I obtained 4 quotes to replace and improve it. Dexteriors offered a competitive price and had completed similar projects to mine (i.e., a 20X20-ft Trex deck with a 10X15-ft screen room). The quality of the work exceeded my expectations and we are quite pleased with the new "room" of the house.

Window FAQ
How do I know it’s time to replace my windows?
Signs include drafts, condensation between panes, cracked frames, difficulty opening or closing, and rising energy bills. If your windows are over 20 years old, it may be more cost-effective to replace them with modern, energy-efficient models. We provide inspections to help you decide.
What are the benefits of energy-efficient windows?
Energy-efficient windows lower heating and cooling costs by reducing heat transfer. They also improve indoor comfort, reduce outside noise, and provide UV protection for furniture and flooring. With advanced glazing and insulated frames, these windows deliver both savings and year-round comfort for your home.
What window styles do you offer?
We provide a wide range of styles, including double-hung, sliding, casement, picture, bay, and bow windows. Each style offers unique benefits, from ventilation to expansive views. During your consultation, we’ll recommend the best designs for your home’s architecture and your functional needs.
How long does window replacement take?
Most window replacements are completed in one to two days, depending on the number of units. Larger or more complex installations, such as custom bay windows, may take slightly longer. We’ll provide a clear timeline before work begins and keep you updated every step of the way.
How much does window replacement cost?
Pricing varies based on window type, size, and features. Vinyl windows are typically the most affordable, while custom and specialty windows come at a higher cost. We provide transparent estimates so you know exactly what to expect—no hidden fees or surprises.
Do you handle disposal of old windows?
Yes. Our team safely removes and disposes of your old windows as part of the service. We also inspect openings for any hidden damage and address it before installing the new units, ensuring your home is protected and ready for long-lasting performance.
Are your windows covered by a warranty?
Yes. Our window products include manufacturer warranties, and our installation work is backed by our guarantee. This ensures peace of mind that your investment is protected. We’ll explain coverage details during your consultation so you know exactly what’s included.
Can new windows really improve home value?
Absolutely. Window replacement is one of the top home improvements for return on investment. Buyers value energy efficiency, comfort, and modern aesthetics. New windows make your home more appealing on the market while delivering practical benefits you enjoy immediately.
