Our company does retrofit window replacement. We have been in business since 1990.We have a 5 star rating and thousands of satisfied customers. NO SALESMEN! You'll deal directly with me the owner. You'll get a better product for less money. With windows it's all about heat loss and they measure that with what they call a U-Factor, the lower the number the better. Being a PUD approved contractor they require a U-Factor of .30. We can get that number down to a .21 for open windows and .18 for non opening windows. A third better but does not cost a third more. And if you live where there is a lot of noise it will almost eliminate it coming through the windows!
"Mike Smith is a very nice and with rich experience guy. He gave me a lot of good advice. His workers worked professionally and cleaned up all the work areas. I am very satisfied with the job. And I will refer him to my friends."

Modernized Exteriors is Washington’s Best Decking ,Siding, Windows, and roofing Residential contractor. We specialize in quality and customer service and we take pride in every job we do.
"Modernized Exteriors seem to have built a decent deck for a decent price but in a somewhat sloppy and dishonest way. First, they left hundreds of pieces of debris including over 100 nails, screws, and other fasteners, and hundreds of pieces of the old deck lying around, including some pieces over six feet long, many with embedded nails sticking out. For months, nearly every time my daughters went out to play they came back with a handful of nails and screws. Second, the old deck had a notch through which the gutter downspout passed to reach the drain in the ground. Instead of cutting a notch for the downspout, they just tossed it behind a bush allowing the gutter to empty directly onto the deck. They promised a 12-month warranty, saying they'd come out to correct any defects. When I mentioned the disconnected gutter they initially said they'd fix it, but then ignored my follow-up messages when I asked them to actually do it. So they may not honor their promises."

We do vinyl windows and vinyl and hardi siding we are a small company low over head so we can keep costs down to you the customer while still providing great products and service I have over 30yrs experience my crews are all certified and trained pros we offer lifetime warranties and glass breakage warranty on top of that warranties are transferable to the next home owner we also have A rating with the BBB and A rating with Angie’s list we offer senior and military discounts give us a call text or email you won’t be sorry.
"We had a few possible leaks in our bedroom windows, they were picture windows that did not open, where we already planned to have them replaced in the long run with ones that open to get some air in the bedroom. So, we requested a few bids and decided to hire WCV to do the replacement. Our house has dozens of large windows, that someday will need to be replaced, so we were looking for a company that had the capability to do a job at that scale some time in the future. Jamie was very clear, straightforward, organized and professional. We knew exactly what to expect and when to expect it. The whole process took about 6 weeks, as the windows had to be manufactured as they were custom, we also had a holiday in the middle of that time period. The guys arrived yesterday on time, where they quickly and professionally installed the windows, cleaned up the mess, and were done! We are very happy with their work."

FAQs for new windows service projects in Mountlake Terrace, WA
Making an existing window bigger always requires some construction, but the extent varies by project. Vertical expansions involve less structural work because they often don't affect load-bearing elements. Even so, any enlargement requires removing siding or drywall, cutting framing members, and installing appropriate support. Non-load-bearing walls allow for simpler modifications, while load-bearing walls require proper headers and structural support. A consultation with a structural engineer is advisable before beginning any window enlargement project.
Building permits are required for window enlargement projects in most municipalities. Since enlarging windows involves structural modifications to your home's exterior walls, local building departments need to review and approve the plans. Permit costs range from $100 to $300, though projects requiring significant structural changes may incur permit fees of $500 or more. Additionally, homes in historic districts or those governed by HOAs may need special approvals. Always check local requirements before beginning work.
An average window enlargement project takes between five hours and three days to complete. Simple projects with minimal structural changes might be finished in five to ten hours, while more complex enlargements requiring significant structural modifications could take up to three days. Factors affecting the timeline include the window's location, wall construction, weather conditions, and the need for specialized materials. The process involves demolition, framing, window installation, and interior/exterior finishing work.
