70+ Years of Home Improvement in Schererville, IN

to Unlock Summer Savings!
When upgrading your home in Schererville, you need a contractor who knows Lake and Porter counties. Someone who’s familiar with the weather patterns and what’s required for exterior home improvements that last season after season.
Trim-A-Seal is a third-generation, locally owned company. Since our beginning in 1970, we've built our reputation on trust and a deep understanding of what Northwest Indiana homes need to stay protected and comfortable year-round.
SunSetter Awnings and Motorized Screens
We install SunSetter retractable awnings, America’s number-one best-selling fabric awnings. You’ll choose from motorized or non-motorized options to cover your patio or deck with shade on demand.
Trim-a-Seal is now your local Costco’s official installation partner for SunSetter awnings. We also install motorized screens for insect and glare control, as well as security shutters for privacy and protection.
Garage Floor Coatings
We apply durable polyurea floor coatings to protect high-traffic concrete areas like garage floors, patios, and walkways. If you are looking for an effective garage floor coating, you may have found “epoxy” options first.
Polyurea is approximately four times stronger than common epoxy and handles Indiana's freeze-thaw cycles far better. It bonds more durably to concrete and resists chipping and peeling.
Window and Door Replacement
If you're experiencing draftiness, sticking frames, and moisture between window panes, these are signals that it’s time for replacement windows. We work with Sunrise and Lang Exteriors to offer high-performance windows for a range of budgets and styles.
Exterior doors take a beating in Northwest Indiana winters, and proper fit and installation matter as much as the product itself. We install Albany entry doors and HomeGuard security and storm doors to enhance the security, efficiency, and polish of your entryways.
Siding and Gutter Services
We address wind-damaged and dated exteriors with full siding replacement as well as repairs to sheathing, soffit, and fascia. CertainTeed and PlyGem siding are proven against Lake County weather, and we offer a wide selection of profiles and colors to match your vision.
Seamless gutters handle Indiana's heavy rainfall by directing water off the roof and away from foundations. We cut gutters to eliminate weak seams and offer gutter cover protection for reduced seasonal cleaning.

Common Questions About Home Improvement in Schererville
Do you serve all of Schererville and the surrounding Lake County area?
Yes, we serve Schererville and the broader Lake County area. If you’re unsure, check the complete list of physical locations and areas we serve.
Why do you recommend polyurea over epoxy for garage floors?
Epoxy is commonly searched for, but it isn’t the most durable option for Indiana's climate. Polyurea is approximately four times stronger than common epoxy and resists chipping and peeling caused by temperature swings.

We carry SunSetter, one of the most recognized names in the category. We’ll help you find the right SunSetter model for your deck or patio.
How long has Trim-A-Seal been serving the Schererville area?
We've served this region since 1950, over 70 years across three generations. That longevity comes from treating each project as the beginning of a relationship, not a completed transaction.

We love our Sunsetter awning! From the time we met with the friendly and helpful salesperson from Trim-A-Seal to the efficient and talented installation crew everyone was courteous and professional.
