"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

FAQs for concrete finishing, overlays & coloring application projects in Concord, NH

With proper care, a stained concrete floor easily lasts 20 years or more. Reapply sealer every two to four years to protect against moisture, scratches, and daily wear. Routine sweeping, occasional damp mopping, and prompt repairs keep the surface looking sharp and protect the slab underneath, preserving both function and resale value.

Stained concrete can crack if the slab is exposed to extreme moisture changes, heavy impacts, or settling. Small hairline cracks are mainly cosmetic, but deeper fractures can affect the finish. Inspect the floor regularly, address moisture issues quickly, and hire a pro for timely repairs. Staying on top of maintenance prevents minor flaws from developing into larger, more costly problems.

The longevity of a concrete stain depends on the product you choose. Acid-based options chemically bond with the slab and are essentially permanent. Water-based stains sit on the surface and can be lightened, darkened, or covered with a new color at a later time. Select the stain type that aligns with your long-term design plans and your willingness to reapply the stain in the future.

You can update the color by cleaning the slab, lightly etching it, and applying a new layer of stain. Re-staining bonds to the concrete and resists peeling far better than paint. For a dramatic shift—such as moving from a dark acid stain to a lighter tone—you may need to grind the surface first. A flooring pro can advise on the best approach for your specific floor.

Stained concrete combines longevity with a modern, custom look. The finish resists heavy foot traffic, moisture, and everyday wear, so upkeep is minimal—routine sweeping and an occasional damp mop are usually enough. Because the color is inside the concrete, it won’t peel or flake like paint. Homebuyers also appreciate its sleek aesthetic and low maintenance, which can add a slight boost to your property's resale value.
