Kitchen & bathroom renovation in Yonkers & NYC
Renovations go wrong when three separate trades point at each other and nobody owns the schedule. Tekno Construction renovates kitchens, bathrooms and full interiors with one licensed, insured team from design to final walk-through — one fixed written quote, one crew, one company responsible for the result.

What we renovate
Everything inside the four walls, handled by our own team rather than a chain of subcontractors you've never met:
- Kitchens — layout changes, cabinetry, countertops, backsplashes, lighting, flooring and appliance hookups
- Bathrooms — full gut renovations, tub-to-walk-in-shower conversions, tile work, vanities and fixtures
- Plumbing & electrical — rerouted and updated to code while the walls are open, when it's cheapest to do right
- Framing & sheetrock — walls moved, opened or built new, taped and finished smooth
- Waterproofing & tile substrates — proper membranes and pans behind every wet wall, connected to the same expertise we bring to building-envelope waterproofing
- Doors, windows & trim — interior doors, entry doors, replacement windows, casings and moldings
- Interior painting — real prep, clean lines, the finish that ties the whole job together
- Basements & full interiors — finishing and remodeling beyond the kitchen and bath
The step cheap renovators skip: waterproofing
Most bathroom renovation failures aren't visible on day one. They show up a year later as loose tiles, a musty smell, a stain on the ceiling below — because the renovator tiled straight over sheetrock and skipped the waterproofing layer entirely. By then the crew is long gone and the fix means gutting the room again.
We treat every bathroom as a wet room. That means a properly sloped and tested shower pan, waterproof membrane on the walls and floor before a single tile goes on, sealed penetrations at every valve and drain, and cement board — never plain sheetrock — behind wet areas. It's the part of the job you'll never see, and it's the part that decides whether your bathroom lasts three years or thirty. As a company that handles structural waterproofing and masonry on buildings across the city, we don't cut corners on water in a bathroom.
Our process, step by step
One team owns the whole job. Here's what actually happens, in order:
- Free on-site design visit — we walk the space with you, take measurements, talk through layout, materials and what's realistic for the building.
- Fixed written quote — a detailed scope with a realistic timeline, delivered within days of the visit. The price you sign is the price you pay unless you change the scope.
- Permits, filings and approvals — where plumbing or electrical work requires DOB filings, or your co-op or condo board requires alteration paperwork and insurance certificates, we handle the whole process with the city and the building. You don't chase paperwork.
- Protection and demolition — floors, hallways and neighboring rooms covered and sealed before demo starts; debris removed daily.
- Rough work behind the walls — plumbing, electrical and framing done while everything is open, then inspected before anything is closed up.
- Waterproofing, then finishes — membranes and substrates first, then tile, cabinetry, counters, fixtures, paint and trim in the right order so no finished surface gets damaged by a later trade.
- Final walk-through and sign-off — we walk the finished space with you, complete a punch list, and clean up like we were never there.
Realistic timelines — and why we won't promise less
Anyone who quotes a one-week gut bathroom over the phone is planning to skip steps. Once work starts, a typical full bathroom renovation runs a few weeks; a full kitchen usually runs several weeks to a couple of months depending on layout changes and material lead times. Cabinets, counters and special-order tile have their own lead times, which is why we lock the schedule and order materials before demolition — not after your kitchen is already torn out.
Your written quote comes with a realistic timeline for your specific job, and we show up when we say we will.
How pricing works
We never price a renovation over the phone, because guessing is how homeowners end up with change orders. Instead:
- Free on-site visit — we measure the space and confirm the full scope before quoting
- Fixed written quote — an itemized scope and price, in writing, with no obligation
- 24-hour response — every call, WhatsApp message and email answered within a day
Your price is determined by:
- Scope — a cosmetic refresh, a full gut, or moved walls and relocated plumbing
- Access — walk-up vs elevator building, protection requirements, building work rules
- Materials — the cabinet, counter, tile and fixture lines you choose
- Filings — whether the work triggers DOB permits or co-op/condo board approvals

Frequently asked questions
How long does a bathroom renovation take?
A typical full gut bathroom runs a few weeks once work starts, depending on scope and material lead times. We order tile and fixtures before demolition so your bathroom isn't torn out while parts sit on backorder, and your written quote includes a realistic timeline for your specific job.
How long does a kitchen renovation take?
Most full kitchen renovations run several weeks to a couple of months, driven mainly by cabinet and countertop lead times and whether walls or plumbing are moving. We lock the schedule and order materials up front, then sequence the trades so the job moves without idle days.
Do I need a permit to renovate a kitchen or bathroom in NYC?
Cosmetic work like painting, cabinets and flooring generally doesn't require permits, but moving plumbing, gas or electrical usually triggers DOB filings — and co-ops and condos add their own alteration approvals. We handle the whole process: permits, filings, board paperwork and inspections.
How much does a kitchen or bathroom renovation cost?
It depends on scope, access, the materials you choose and whether filings are required — which is why we quote only after a free on-site visit. You get a fixed written quote with no obligation, and we respond to every inquiry within 24 hours.
Can I live in my home during the renovation?
Usually, yes. We seal off the work area, protect floors and hallways, and keep a second bathroom functional whenever the layout allows. For kitchen jobs we can help you plan a temporary setup so the disruption stays manageable.
What does bathroom waterproofing involve, and why does it matter?
Before any tile goes on, we install a sloped, tested shower pan, waterproof membrane on wet walls and floors, cement board instead of plain sheetrock, and sealed penetrations at valves and drains. Skipping this layer is the most common shortcut in cheap renovations — and the reason tiled showers leak into the apartment below a year later.
Do you work in co-ops and condos?
Yes — a large share of our renovation work is in co-op and condo buildings. We're licensed and insured, we provide the certificates boards require, and we handle alteration agreements, building work rules and scheduling with management so approvals don't stall your start date.
What areas do you serve?
We serve New York only: Yonkers, the Bronx, Manhattan, Brooklyn, Queens and Westchester County, from our headquarters at 137 Homewood Ave in Yonkers. We respond to every inquiry within 24 hours.
