About our new build mastic in Compton
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you have joints pulling apart as timber shrinks and shower seals failing in the first year or two, we can put it right.
Older homes in small places like Compton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, you get the same 12-month guarantee in Compton and across West Berkshire.

How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The type of sealant required
- How many areas need sealing
- The size of the job
- How easy the joints are to reach
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Photos by email, if that is easy

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. Sealant work across the plot is covered.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours in a single home. In a small place like Compton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

New build mastic in Compton: local notes

How to look after the new joints
So the new joints stay in good condition:
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.

Signs you need new build mastic in Compton
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
Around Compton, as everywhere, new build mastic is only as good as the preparation behind it.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
