At Connecticut Custom Creations™, we specialize in transforming kitchens, bathrooms, basements, and attics into beautiful, functional spaces tailored to your needs. We take great pride in helping people build their dream homes, a core value that drives everything we do. As an owner-operated business with over a decade of experience, I bring seasoned expertise to every project, no matter the size. Whether it’s a small renovation or a large-scale remodel, we’re committed to delivering exceptional results with care and precision.

"Dustin and CCC did wonderful work creating a new bathroom and remodeling a bedroom for our house. What was most positive was Dustin’s energetic interest in the project, dedication to seeing the project through to make it come out with high quality, and persistently spirited good will. There were two aspects that didn’t work quite optimally: (1) The crew took much longer to finish than they promised (the original time was “1-month +” but over two months passed and there were still lingering issues---see below.) If you hire them, I recommend having it written into the contract exactly when it will start and end, including a specification of what the consequences will be if the job isn’t done on time. (2) They didn’t know what to do with our laminated wood floors. They needed to put down protection for the dining room floor which was damaged by the construction traffic, and they had trouble patching and refinishing the floor in the bedroom after removing a wall. When I asked Dustin to address (2), to his credit he was ready to bring in a floor refinishing specialist to fix the issues at a very favorable price to us. At that point, unfortunately, we couldn’t afford the interruption it would cause to have this repair done at that moment. In response, Dustin gave us a discount so we can address these issues with a profession flooring company in the future when we’ll have a good opportunity to vacate the house for this purpose. I recommend that if you need wood floor work done, you make sure there is an agreement in the contract to have somebody with wood floor expertise address that part. In all, Dustin was generous and willing to try to work with us when there were issues. I know that his company has also been generous about helping people who were in need in the past. This is a quality that I particularly admire in a company, so we still feel very positive toward CCC, but I have identified the issues we had in hopes that they won’t be issues for other clients in the future."

Basement Waterproofing questions, answered by experts

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.
