How we quote for new build mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The size of the job
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What we need to know
Photos help, but a description is a good start. Please mention:
- If someone has resealed it before
- Whether it’s a home or a business
- Roughly how big the job is
- Where the job is, and your postcode
We don’t publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, phone 0345 464 0079 or drop us an email.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. For a village or hamlet like Compton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Signs you need new build mastic in Compton
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
These are the problems we’re asked about most:
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
Around Compton, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Who turns up on the day
- Whether all the old sealant comes out first
- Whether they’re fully insured
- What happens if the job turns out different
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Watch for new gaps as the house dries out
- Raise failed sealant with the developer while you’re covered
- Record problems with dated photos
- Act quickly if a seal starts to leak
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.
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.
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In a small place like Compton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

Landlords, agents and businesses in Compton
For anyone letting property in or around Compton, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
