"I can’t say nice enough things about the process of working with Martin. We decided to finish our basement, including a full bathroom, while I was pregnant and wanted the job wrapped up before the baby came, which gave a very hard deadline. Not only was Martin able to work with us contacting him two months out on this project, he was so responsive during the process, gave us great ideas, and kept us well-informed on everything that was happening with the project. From start to finish, we always felt that Martin was knowledgeable about what he was doing and didn’t seem bothered when we had last minute changes. The entire team was so clean, which gave me comfort given that I was pregnant at the time, and they were able to complete everything before the baby came. If I had more basements, I would definitely call Martin!"

Our commitment to the highest standards of quality and craftsmanship, alongside personal attention to clients' projects, creates an opportunity to not only build beautiful homes and additions, but also lasting relationships.

"We had Eric add an addition to our garage and extend the roof over the front porch. We also had the front porch replaced and had new shingles on the whole house. It was a fairly simple job complicated by lots of rain. We were kept informed of any delays and when contractors would be working. The job came out looking great. The best compliment you can say about an addition is that it looks like it was always that way and it certainly does in this case. I highly recommend Somrok Inc."

Basement Leak Repair questions, answered by experts

The frequency with which a French drain clogs depends on various factors, such as the amount of debris that enters the pipe, the quality of the French drain installation, the type of grate and filter used, and how often it is maintained. That’s why it’s recommended to clean your French drain at least once a year, whether it is clogged or not. This can prevent clogs and increase the lifespan of your drain.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

There are several reasons why you may find water dripping through your ceiling. This leak could be the result of a plumbing issue or a damaged roof. It’s important to determine the source of the leak before it causes damage to your home and belongings. Taking steps to catch the water immediately will help with additional issues.

The best way to fix dampness in walls is to find the root cause and fix the underlying issue. After that, you’ll need to dry the wall with a heavy-duty fan and potentially a dehumidifier. If the wall has water damage, you can remove the damaged drywall, patch it with a new piece, and then paint it to match the rest of the wall.
