What We Repair
Caulking, Grout & Weatherstripping — Every Common Seal Job
Whether it’s a bathroom that’s been collecting mildew around the tub or a front door that lets in cold air all winter — NorTech handles the full range of sealing and weatherproofing repairs in one visit.
Tub & Shower Re-Caulking
Old caulk stripped completely, surface cleaned and dried, and fresh mold-resistant silicone applied around tub surrounds, shower pans, and shower doors.
Kitchen Caulking
Countertop-to-backsplash seams, sink perimeters, and cabinet-to-wall gaps re-caulked with food-safe, mold-resistant material after full removal of existing caulk.
Grout Repair & Regrouting
Cracked, crumbling, stained, or missing grout removed and replaced with color-matched grout — walls, floors, and shower surrounds without full retiling.
Door Weatherstripping Replacement
Door sweeps, compression strips, and V-strip seals replaced on entry doors, garage doors, and interior doors — selected to match frame dimensions and door type.
Window Weatherstripping & Sealing
Window channel weatherstripping replaced and exterior window perimeters re-caulked to eliminate drafts, water intrusion, and air leakage around frames.
Exterior Caulking
Gaps around exterior door and window frames, siding seams, and utility penetrations sealed with paintable exterior-grade caulk to block moisture and air infiltration.
Warning Signs
Signs Your Caulk, Grout, or Weatherstripping Needs Attention
These problems don’t fix themselves — and the longer they’re ignored, the more damage accumulates behind the surface.
Black or Pink Discoloration
Mold and mildew growing in caulk lines means the seal has failed and moisture is getting behind the surface.
Cracked or Shrinking Caulk
Gaps in caulk lines allow water to penetrate behind tile and into wall cavities — leading to rot and mold over time.
Crumbling or Missing Grout
Exposed tile edges without grout allow water behind tile — eventually loosening the entire installation.
Drafts Around Doors or Windows
Feeling air movement around a closed door or window is a direct sign that weatherstripping has compressed, torn, or pulled away.
Light Visible Around Door Frame
If you can see daylight around a closed exterior door, the weatherstripping seal is completely compromised.
Rising Energy Bills
Failing door and window seals are a leading cause of heating and cooling loss — fixing them is one of the highest-ROI home maintenance tasks available.
Before Your Technician Arrives
A few simple steps before your caulking or grout repair appointment will keep the job on schedule and ensure the best possible result.
- For tub and shower re-caulking — ensure the surface is dry. The technician needs a dry surface to apply new caulk, so avoid using the shower for at least 12 hours before the appointment.
- Clear the area around the repair zone — remove toiletries, bath mats, and items stored near the tub, shower, or countertop being worked on.
- For grout repair — note the tile color and grout color if possible, or have a tile sample available. Your technician will work to match the existing grout color as closely as possible.
- Plan not to use the sealed area for at least 24 hours after the job — caulk and grout need time to cure before water or heavy contact.
Pricing
What Caulking, Grout & Weatherstripping Repair Costs
Pricing depends on the type of repair, the number of locations, material type required, and your area. A single tub re-caulk is a straightforward job — a bathroom with full grout repair, re-caulking, and door weatherstripping is a larger scope.
Factors that affect cost: number of repair locations, repair type, surface area, material selection, and whether mold remediation of the existing surface is needed before sealing. Get an accurate estimate by submitting a quote request with your details.
Customer Reviews
What Customers Say About NorTech Caulking & Grout Repair
“The caulk around my tub had been black and cracked for years. NorTech stripped it all, cleaned the surface, and laid a perfectly clean white bead. Looks brand new. Took about an hour.”
Tanya H.
“Grout repair in my master bathroom — about a dozen cracked lines and two spots where grout was completely gone. Tech color-matched perfectly and the repair blends right in with the existing tile.”
Samuel G.
“Had both bathroom re-caulked and the front door weatherstripping replaced in one visit. Door seal is a huge improvement — no more draft in winter. Caulk looks clean. Minor scheduling hiccup but work was solid.”
Irene P.
“Kitchen countertop caulk was pulling away from the backsplash and I kept ignoring it. NorTech pulled it all out and redid the whole perimeter. Clean lines, no gaps, and they used a color that matches perfectly.”
Keisha R.
“Tub re-caulk job was done correctly and looks good. I was expecting them to also clean the tile but that wasn’t included — my misunderstanding. The caulk itself is clean and well applied.”
Martin V.
“Exterior caulking around three windows that were leaking air and water during storms. Tech caulked every gap, smooth and neat. Haven’t had a single leak since — including through two heavy rainstorms.”
Donna C.
FAQ
Caulking, Grout & Weatherstripping — Frequently Asked Questions
Specific questions about NorTech’s sealing and weatherproofing service, process, and what to expect.
What caulking and grout services does NorTech provide?
NorTech provides bathroom and kitchen re-caulking, grout repair and regrouting, weatherstripping replacement on doors and windows, exterior caulking around windows and doors, and tub and shower surround sealing. Old caulk is fully removed and surfaces are cleaned before any new material is applied.
How much does caulking or grout repair cost?
Cost depends on the area being sealed, the number of locations, material type needed, and your location. NorTech provides a free upfront estimate before any work begins. Submit a quote request describing your specific repair for accurate pricing.
Does NorTech remove the old caulk before applying new?
Yes. Old caulk is fully stripped before any new material is applied. Applying new caulk over old caulk leads to poor adhesion and early failure — NorTech always starts from a clean surface.
How long does new caulk need to cure before using the shower or tub?
Most silicone and siliconized latex caulks need 24 hours to fully cure before water exposure. Your technician will advise on the specific cure time for the product used in your installation.
Can NorTech repair cracked or missing grout without retiling?
Yes. Cracked, crumbling, or missing grout lines are repaired by removing the damaged grout and applying fresh matching grout. Full retiling is not required for grout repair in most cases.
What types of weatherstripping does NorTech replace?
NorTech replaces door weatherstripping including door sweeps, compression strips, foam tape, and V-strip seals. Window weatherstripping replacement is also available. New weatherstripping is selected to match the door or window type and existing channel dimensions.
How do I know if my weatherstripping needs replacing?
Signs of failing weatherstripping include drafts around doors or windows, visible light gaps around door frames, increased energy bills, insects entering around sealed doors, or visible cracking, compression, or tearing of the existing strip material.
Is caulking and grout repair covered by a warranty?
Yes. All NorTech caulking, grout, and weatherstripping work is backed by a 1-year labor warranty. If any workmanship issue arises within 12 months, we return and correct it at no additional labor cost.
