A1 Professional came quickly to give me a quote for a large deck. Gave me a great price and started on time. They took care of permits and was here every day until they finished. They are the best I’ve ever worked with!!

Great design and build — new deck, clearing trees and a pathway to my lake. Quality exceeded expectations, completion time was impressive and the price was reasonable. Will use them again.

Frequently Asked Questions

How much does it cost to replace windows on a lakefront home?

Lakefront homes sometimes need extra moisture protection at the frame, which can affect the price. A1 Pro inspects your home and gives you an exact number on the spot.

How long does window installation take on a waterfront property?

Most installations take one to two days, depending on how many windows or doors are being replaced and how the home sits relative to the water. A1 Pro schedules the full job upfront.

Do lakefront homes need different windows than homes further inland?

Often, yes. Homes closer to the water benefit from materials that resist moisture and wind better, like fiberglass or high-grade vinyl. A1 Pro can recommend the right fit based on your home’s exposure.

Will new windows help with moisture problems near the lake?

In most cases, yes. Properly installed windows and doors seal out the moisture that older frames let through. A1 Pro backs every installation with a 5-year transferable craftsmanship warranty in case issues arise later.
