"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"Living on Cape Cod & the islands limits us with options. I tried to get quotes from local vendors but was told my chimney is to large for their capabilities. Kings Masknary can by for an estimate and was able to diagnose the issues and put a plan in to fix it immediately. I was impressed that they worked thru a weekend in the cold to fix my problem. They did exactly what they said they would do and guaranteed their work for 20 years. What more could you ask for. Was great working with them and would call them again but now . What a great feeling to know that if there is an issue, they will stand by their work."

"I highly recommend Custom Coating. My mahogany deck hasn t looked so good since it was installed over 15 years ago; they power washed, sanded and stained it back to looking new. The only drawback was this high heat and humidity which made drying process slow. I would have them come for maintenance next time but in early spring."

"I have now had 4 pickups from this company. Each time it has been with different items: I have had my kitchen remodeled,  a deck torn down and rebuilt, a new roof put on, old fencing disc arded, and a yard cleanup. The only difference in pricing was for the roofing and even though ti was more money it was STILL CHEAPER than a dumpster!!! I don't know how these guys do it, but they pickup on time, without issue andfor the cost quoted. I have turned each of my contractors onto them - now they are using them. SO MUCH cheaper and better service than any dumpster company I have used!"

Basement Waterproofing questions, answered by experts

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

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.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.
