- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
New build mastic for homes and businesses in Carrington
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on kitchens, windows & doors and skirting & floors, and people most often call us about shower seals failing in the first year or two and worktop and upstand sealant coming away.
For a place like Carrington, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What we’re called out for in Carrington
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Any of these means the joints need attention:
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
If you’ve bought a new home near Gorebridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Show homes
- Bathrooms & en suites
- Windows & doors
- Kitchens
- Plot handovers
- Skirting & floors
Looking after it afterwards
So the new joints stay in good condition:
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours in a single home. Outdoor work around Carrington depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Landlords, agents and businesses in Carrington
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
