RWN Property Services is a general contracting company that specializes in land care, building maintenance, residential construction and excavation. We have 2 divisions within the company, Basement Authorities which specializes in basement waterproofing, structural foundation repair, dehumidification and helical piering and NuRock Creations which specializes in Decorative concrete, outdoor living, decorative hand carved structural retaining walls, and flat work.

"It has two years of trying to work with Robert Nelson of RWN over simple installation of stairs. In emails he said he would remove the and redo the steps but he never returned. Steps were supposed to replicate in color and texture of two granite steps in place. As you can see in the photo they aren't. Frustrated I asked Small Claims court to help. Thankfully they did and in my favor."

Basement Waterproofing, Crawl Space & Foundation Repair experts since 1991. Free estimates & inspections.

"I had a basement waterproofing project done by TC Hafford in March costing over 19K. It is now July and my basement is full of water, once again,on this rainy day. I have been back and forth with this company for months, and after sending someone in who finally admitted to faulty installation, I am still waiting for them to fix their mistakes. I absolutely would never recommend this company to anyone."

"Our experience with New Leaf Construction in December led us back to hiring them again for a few additional projects we wanted completed outside this spring. The remodel of our firm over the winter was very successful and it was a pleasure to work with their crew. Their professionalism showed throughout the entirety of the project, from the quality of their work, sensitivity to our timeline, accommodating the needs of our business with as little interruption as possible, cleanliness of their work area, attention to detail, and staying on budget. I highly recommend New Leaf Construction."

Basement Waterproofing questions, answered by experts

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
