"We had a great experience working with Wes from Boynton Builders LLC! We had a pretty extensive basement remodel / conversion to living space project that we needed help on, and we are extremely happy all aspects of this project using Boynton Builders LLC. Wes responded quickly to a voice message I left, was able to quickly schedule a time to visit to discuss our intended Scope of Work (which also involved another project re-enforcing a carrying beam and support post in our detached garage) after which he quickly provided detailed quote that fortunately fell with our budget. We agreed to move forward, and Wes went to the Town Office for us and took care of the Building Permit and were able to start our project within a couple of weeks and the work proceeded at a good clip with every stage discussed being performed in the order identified from the onset. As the project progressed, we added an additional phase to the scope of work (Install Flooring and a new double door) and he quickly estimated the additional cost got the next phase into his schedule about a week after the completion of the first / original project. Throughout the whole project Wes was pleasant, professional, motivated and productive and open to any requests for change as the space began to be completed and new ideas came into play as we were better able to visualize the final result. Wes completed all of the work on time and within the budget/ and additional scope estimates. We already have the next project planned and will be using Boynton Builders LLC again. Any friends that have seen the completed project state that it is "an incredible transformation" and we are proud to welcome friends into a space that was once an embarrassment. I would also like to mention that I originally reached out and left the same voicemail (one right after the other) for three different contractors and Wes was the only callback received, and that was within a couple hours."

"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 furnace wasn’t working. It’s only 5 years old. We called them and they came out 3 times…..never fixed our furnace. They charged us $3,100 of which we paid $1700. We refused to pay them at the 3rd visit because they claimed that it was the thermostat which wasn’t working. Why does it take 3 visits of 3-5 hours per visit to work on a thermostat? When I spoke with Dana, the manager, the next day he stated that Lucas, the tech, had to call tech support to get help with putting in a new thermostat. They took down our thermostat which had been working for 5 years with no issues. They put in a new thermostat, but they didn’t know how to get it to work. Dana was very angry when I told him we would not pay for the 3rd visit. He started yelling at me. I couldn’t believe it. I told him not to come back. Bad, bad customer service and they are a bunch of idiots. DO NOT HIRE THEM!"

Basement Leak Repair questions, answered by experts

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

While both a channel drain and a French drain serve a similar purpose, a French drain is designed to prevent groundwater from causing flooding issues. This type of drain system goes underneath the soil and is completely surrounded by soil and rock. A channel drain, also called a trench drain, removes surface water before it ever enters the ground—hence the concrete and above-ground installation method.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.
