New build mastic in Great Hormead
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you have skirting joints opening in the first winter and internal frame sealant that has split, we can put it right, whatever the surface.
Around Great Hormead, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

What affects the cost of new build mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The old material and how stubborn it is
- Access and height
- Any working-time requirements on site
- Any mould that needs treating
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Helping us quote
When you call or email, these details help:
- The address or postcode of the job
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
How the job changes by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Honest limits
Before you book, it’s worth knowing the limits too:
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Windows & doors
- Plot handovers

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
New homes and floors in Great Hormead
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Do you need new build mastic in Great Hormead?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Signs it’s time to call us include:
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Shower seals failing in the first year or two
Around Great Hormead, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Don’t seal over failed sealant yourself
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
