Woolhampton New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes in Woolhampton, with a one-year guarantee on every job. Ask us for a quote.
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours in a single home. Somewhere as small as Woolhampton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Advice
New build mastic in Woolhampton
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have gaps behind new kitchen upstands and cracked caulk along new skirting, we can help, on plot handovers, skirting & floors and windows & doors alike.
Older homes in small places like Woolhampton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we’re called out for in Woolhampton
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
It’s worth asking for a quote if you see:
- Plot mastic for developers ahead of handover
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
For new homes near Midgham station, it’s worth checking the sealant early, while snags are still fresh.

Woolhampton questions
Do you work for landlords with property near Midgham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is Woolhampton in your area for new build mastic?
Yes. We work across London and the South East, and Woolhampton is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Get in touch with the number of plots and the scope and we’ll quote.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Do you have insurance?
Yes. Full insurance covers our work.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid scourers and strong chemicals on sealant
- Record problems with dated pictures
- Keep water off fresh sealant until it has cured
- Look at the sealant regularly in the first couple of years
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.
