The Local Reality: Fogged Glass and Invisible Rot

Why do standard windows fail so quickly in our town?

The Inland Threat (Forestdale): Homes tucked into Sandwich’s dense pine forests deal with heavy shade and high humidity. This environment causes older wooden frames to swell, stick, and silently rot from the inside out, creating invisible drafts that drain your heating budget.
The Coastal Threat (Town Neck & East Sandwich): Properties facing the Bay endure relentless freezing winds. This corrosive air degrades cheap weatherstripping and drives heavy rain past failing seals straight into your wall cavities.

Our Full-Frame Extraction Strategy

How do we permanently secure your home against the elements?

Complete Frame Eradication

We strip the failing window or door entirely down to the rough structural opening. This guarantees we can identify and eradicate hidden fungal decay before installing the new unit.

Advanced Hydro-Flashing

To combat wind-driven coastal rain, we integrate premium sill pans and waterproof barrier tapes directly into your home's exterior envelope.

High-Density Thermal Sealing

Instead of using outdated fiberglass stuffing that sags over time, we apply precision low-expansion foam around the entire frame to lock in your climate control and dampen outside noise.

The Structural Risk of "Pocket" Inserts

Why shouldn’t I just install a window insert? A “pocket” replacement is an industry shortcut where contractors leave your old, weather-beaten wooden frame attached to the house and simply slide a smaller vinyl window inside. In Sandwich, this is a significant liability. It drastically reduces your natural sunlight, relies on temporary caulking, and permanently traps active wood rot inside your walls. We exclusively perform full-frame replacements to ensure your new products are anchored to healthy, sound wood.

Our in-house teams deliver flawless integration.

 Trustindex verifies that the original source of the review is Google. Yuri, my whole career has been spent in the construction business. I am particularly impressed by your company. From sales and estimating through scheduling and field coordinating all of your assets have been far above average. Ty made a great presentation as a sales representative of your company and Iago supervised a very competent crew, responded to my concerns about schedule and finished this job early with little interruption in our lives. Thank you again for your excellent service.

 Trustindex verifies that the original source of the review is Google. Ty Soares, who works for this company, is a kind individual, a man who can be relied on and trusted. He found me stranded and lost with my two dogs in a conservation area parking lot and took time out of his busy day to give my dogs water and he drove me and my dogs to my car which was a few miles away. I am getting an estimate for new windows from this company because if their employees are like Ty, that is who I want to do business with.

 Trustindex verifies that the original source of the review is Google. Thanks to Yuri, Ty, Gabriel and the entire Lions Roofing Team for an amazing job installing our new roof. From start to finish, this is a first class company that makes sure they deliver what they promise and that the customer is satisfied when the job is complete. Ty did a thorough pre-inspection of both the inside and outside of the roof area, eaves ridge and gutters. The written quote was one of the best I've ever received and they provided copies of their insurance and license for piece of mind. Project Manager Gabriel was on site before, during and after completion, and always available to answer any questions. The overall job was completed in one day, with a follow-up day for a couple of hours to finish a couple of additional requests I had. One point I must bring up was how clean the job site was after they were done. If you have any roofing or siding projects coming up. I give my endorsement to Lions Siding and Roofing!
Thanks again!
