"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"Serge did much more than flooring; he also installed electrical (lighting/ceiling fan & outlets) , bathroom vanities and enclosed an indoor storage area with custom doors. He is fair and an excellent worker. We especially appreciate his prompt communication. That work was done summer/fall 2022. Heâ s back now (summer 2023) for more home improvements."

"Had Groundworks install a drainage system and sump pump in our home’s crawl space. Anthony and his crew, Jordon, Uriel, and James were Outstanding. It was a three day job. They were on time every day and worked their tails off each day. It was a muddy job in cramped quarters. They never complained. Anthony kept me updated on the progress they made each day. Anthony shared pictures of the job as it progressed. They cleaned up the job site each day. Anthony went over all the details at the completion of the job and answered all of my questions. The whole process was Great. From the initial inspection done by Kristy to the office staff and the installation. The communication was also Great. I highly recommend Groundworks for a complete and thorough job."

"The guy I spoke to was super professional in person and on the phone. He was able to set clear expectations for what could be done and gave accurate estimates for the work. The gravel they laid out as an extension to my driveway looks fantastic, and I’ll definitely be calling back if I need any more work done!"

"We had a foot of water in our crawl space after the snow and 6 in. of rain from the December 2021 storms. I had called several companies to come out to take a look and give quotes. Ethan from diversified was the 3rd quote we received. Ethan explained the issue, explained what they would do to remedy it, and answered all my questions. He sent me the quote which was very resonable. BE SURE TO GET SEVERAL QUOTES. ONE COMPANY QUOTED US DOUBLE OF WHAT WE PAID DIVERSIFIED. They were able to get a team out two days later. The team was on time, professional, and did really good work. We ended up needing a sump pump due to ground water coming up. They applied a mold application and completed the work in a day. I highly recommend these guys and did my research prior to having them do the work. I am very impressed and happy we chose them."

"Great company, called about a backed up toilet. They were able to come out first thing the following morning. Jordan and Jeremy showed up in the freezing cold and cleared the clog on the drain line very quickly. They also took extra time to scope and jet the line and found a busted pipe and extensive roots in the lines as well. They got everything cleaned out very quickly and left me with a product to help keep the roots away till we can get the pipe fixed and possibly get a liner installed in the future. I would recommend Zoom drain as they were fast, professional and reasonably priced. Thank you for great service."

"When I asked for service because of a water leak, they gave me a next-day appointment, on Friday. Next day they called and said they couldn't come, but would come between 1 and 7 PM on Tuesday. Waited all afternoon on Tuesday and nothing, not even a call. Wednesday I called to report the failure and was told management would be notified. Thursday afternoon I called and was given an appointment between 1 and 7 PM the next day, Friday. On Friday an expert plumber showed up an hour early and did a marvelous job. Seemed to cost an arm and a leg, but complete and professional, along with good explanations of everything."

Basement Waterproofing questions, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.
