Daniel did some tile work for me and I couldn’t be happier with how everything turned out. Absolutely amazing work and craftsmanship. He showed up on time, was very professional throughout the whole job, and did a fantastic job. You can tell he takes pride in his work and pays attention to the little details. Good, reliable contractors aren’t always easy to find, and Daniel is definitely one of them. The quality of the work was excellent, everything was done right, and he was worth every penny. I will definitely use him again and wouldn’t hesitate to recommend him to anyone looking for quality tile work. Highly recommend! Daniel, thank you so much for getting the job done on short notice.

Waterproofing · New Britain
Why waterproofing matters more in New Britain than almost anywhere
More than half of New Britain's homes are in two-, three- or multi-family buildings, the highest share of any town we serve. In a three-decker on Broad Street or near CCSU, the second-floor shower sits directly over the first-floor kitchen, and the framing between them is old. When an old mud pan or a mastic-set surround fails, the damage shows up as a stain in the apartment below, and by then the joists have been wet for a long time.
That is why we build every New Britain shower as a sealed system, not a tiled box: a sloped pan with a bonded membrane (**Schluter-KERDI** or a liquid-applied equivalent), membrane carried up the walls and out onto the bathroom floor, sealed seams and pipe penetrations, and a twenty-four-hour flood test before a single tile goes on. In an owner-occupied cape or ranch the same system protects your own ceiling. We are six minutes away, which makes the flood-test visit simple.
Not sure how much of this your home needs? Start here: the five layers behind a shower that lasts It takes five minutes and saves guessing.
In New Britain we waterproof every shower with a bonded system: Schluter-KERDI membrane, pre-sloped pans, curbs and a flood test before a single tile goes down.

What we find behind New Britain showers
Mortar beds with no membrane
Pre-1960 tub surrounds were a mortar bed over tar paper and lath: good masonry, but water-resistant rather than waterproof. Once the tile is off we take the bed out to the studs and start from a dry, flat frame.
Wet framing below the pan
In stacked units we check the subfloor and joists at the drain from below where there is access. Soft or stained wood is replaced or sistered before the new pan; tiling over it would only hide the problem.
Old drains
Cast-iron and galvanized drains often will not take a modern bonding flange. The plumber replaces the drain assembly under a permit while the floor is open, and the new membrane is bonded directly to the flange.
Permits in New Britain
Does this work need a permit?
Under the 2022 Connecticut State Building Code (§R105.2), tiling, cabinets, countertops and similar finish work that involves no structural change is exempt from a building permit. Plumbing changes such as a new valve or a moved drain, and any electrical work, are permitted separately by the licensed plumber or electrician who performs them. We tell you which items in your scope apply before work starts.

Shower Waterproofing in New Britain: Questions
No. Daniel and his own crew do the tile work. We do not hand your job to a third-party installer, so the same people who set the tile are the ones in your house every day of the install, and you deal with one company from the estimate through the final clean-up.
Stop using the shower and have it looked at. A ceiling stain under a tiled shower usually points to a pan or a wall joint that has failed, and the fix is a rebuild of the wet area on a bonded membrane, not a regrout. We can inspect from below, open a test area and tell you honestly what the shower needs.
Yes. The drain is plugged, the pan filled to just below the curb, marked, and left for 24 hours before tile. It costs a day and catches the problem that would otherwise cost a ceiling. You are welcome to see the water line the next morning.
No. A bonded membrane has to be on the substrate under the tile, so it means removing the tile and backer. If your shower is sound and just has failing grout or silicone, our repair service can address that; if the pan or walls are wet, the wet area is rebuilt.
The waterproofing and tile are exempt from a building permit under the 2022 Connecticut State Building Code. Replacing the drain assembly or the valve is plumbing work that the plumber permits through the City of New Britain's Department of Licenses, Permits and Inspections at 27 West Main Street. We sequence the inspection between rough-in and membrane.
We build the pan, then go over it with a bonded waterproofing membrane such as a Schluter-KERDI style sheet or a liquid-applied one where the geometry calls for it. The membrane runs over the pan, up the walls, around the curb, and over every seam, corner and valve penetration, and we hold a twenty-four-hour flood test before any tile goes down. If a drop moves, we find it while it is still inexpensive to fix.
Only sometimes, and only when the old tile passes the checks: solidly bonded everywhere when you tap it, flat, and structurally sound, with enough give at the outlets, counters and doors to absorb the added thickness. When it fails any of those, tiling over it locks the problem in. On a wet area we almost always take it down to the substrate instead.
