"John Phillpis Construction (JPC) was a great find. First, he was recommended by my Real Estate broker. That’s a plus BTW. JPC started by fixing a consistent leak in a downstairs below ground bedroom. It wasn’t an easy fix. His men had to dig a trench the entire length of the house. Install drainage pipes and stuff like that. It never will leak again! ... Then they fixed a wall I had to crawl around for 9 years. But on simple jobs he works alone. Like buying and installing 2 new fans from Home Depot, a Samsung TV from Amazon and dumping 3 junk TiVo’s. Today, he fixed bathtub fixtures I couldn’t get anyone to fix for 8+ years. He found the American Standard(?) valves in an outta the way plumbing store in the boonies. After visiting 2 better known places. The tub/hot tub works now ... finally! No cutting tile or replacing $500 fixtures! I have a long list of jobs awaiting... I’m glad I found John Phillpis. I hope this helps"

"We needed a new roof 26 years after MRC had last done our roof. We worked with Mark Hill to find a roof coating that would cool our house. He recommended a product called Permalock Metal roofing and a silicone coating for our flat roof. We have had the roof for 1 year and this summer has been nice and cool. Thank you to the team at MRC."

Basement Waterproofing questions, answered by experts

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.
