"HIired Serge Home Improvement, i for a partial remodel of the kids bath-new shower surround and flooring. During the time, I got the bid and he started work, the laundry room flooded and I asked if he could work on that too. Serge worked with the insurance adjustor and myself to bring the bid in at the insurance companies expectations. He had the laundry room up and running in a couple of days, with lovely new trim. This was a huge relief, as I had now washer for 2 weeks and laundry was piling up. Most of the bids I got for the bathroom work were in $15-$20K or more range. Serge's costs were reasonable and we agreed on what he'd provide and what I'd provide-tile and surround. When asked why the tub should be replaced he explained he wanted to make sure the plumbing was correct. He was right about that, the previous owner had "tiled" himself and done the plumbing. It was mess but Serge fixed it. Furthermore, he used lots of water proofing which gave me peace of mind as the kids splash like crazy. In 2 weeks, the bathroom was finished, and ready to use. I had him re-caulk my tub, and replace light fixtures in the dinning room and family room. It cost a small bit more than I budgeted, but having done remodels in the past I expected that. We are thrilled with the updated bathroom and new light fixtures. I a already discussing future projects with Serge. The best thing about Serge is his doesn't do mind doing projects on your house off and on. My previous contractor stopped taking my projects, because "projects to small and piece meal". Thankfully, Serge doesn't have that attitude."

They did the clearing out of the old cupboards and flooring and used my idea to give our family a masterpiece. I recommend them for any renovations, they did an excellent job."

"I strongly recommend Bzr. We found them on Houzz. We started with a kitchen remodel and felt good about moving forward with our next projects with them. We then started our bathrooms. Sean and his crew did an amazing job. They were very respectful about our place, patched up and protect our home. Sean was very helpful with choosing and delivering materials. Overall we had an outstanding experience with them. Gaby was also such a pleasure to work with. Without a doubt we would hire them again."

Basement Remodel questions, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.
