"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"

I am a self-taught artist, initially drawn to experiment with pastels and colored pencil, and now working with acrylic on canvas. My art speaks for itself.

"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

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.

Regularly inspect for leaks, repaint wood surfaces, and reinforce weak joints to prevent deterioration.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.
