Stop Cracks, Gaps, and Drafts
Exteriors We Seal and Waterproof
Exterior sealing is vital for protecting your property from water intrusion, energy loss, and long-term structural damage. We specialize in sealing and waterproofing the most vulnerable points of your building’s exterior, where water, air, and pests are most likely to sneak in. Our in-house crew seals around windows, doors, siding transitions, vents, joints, and penetrations to prevent moisture damage and energy loss.
Brick Walls
Brick is strong, but it’s not waterproof. We use high-quality, breathable masonry sealants to protect brick walls from moisture intrusion while allowing vapor to escape.
Joints and Corners
Joints and corners are prime spots for leaks. We apply flexible, long-lasting exterior caulking to seal the transitions between materials, such as siding, trim, and stucco.
Doors and Window Trim
We meticulously inspect, caulk, and seal all door and window trim to prevent water infiltration and thermal inefficiency—two of the most common culprits behind structural damage.
And more!
We don’t just stop at doors, windows, or siding. Our team inspects and seals everything, from roof flashing to foundation transitions, and beyond.

TESTIMONIALS
Saving Your Family Time and Money With Proper Caulking
You have better things to do than worry about whether or not your exteriors are sealed, protected, and holding up to the elements. That’s our job—and we take it personally. But don’t just take our word for it. Our clients consistently mention the same things: top-tier craftsmanship, honest communication, and crews that treat every home as if it were their own.
Craig and his team were fantastic throughout our long window and door replacement project—respectful, clean, and communicative.
The Hwang Family, Downingtown
They absolutely go above and beyond, and we are very grateful to them. Craig Hannum has handled every possible issue with care and patience… They built a ramp for my husband, recovering from surgery, so he could access our home. Again, we compliment you on a job well done!
The Boaman Family, Chester Springs
The quality of workmanship has been superior. Craig’s team has excellent work ethics and attention to detail. They even fixed misaligned windows we didn’t notice and resolved a fireplace draft. Trustworthy and professional.
The Sheth Family, West Chester
These guys are the best—very professional, great communicators, and meticulous. I don’t know how they replaced every window without leaving a mark inside the house, but they did. Highly recommend.
The Roconni Family, West Chester
