New build mastic in St Clement's
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. Typical jobs include frame joints opening as the plaster dries and second-fix sealing on new plots, on plot handovers, bathrooms & en suites and show homes.
If you’ve bought a new home in or near St Clement's, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Our work is backed for twelve months.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
Questions from St Clement's
Can you help a landlord with a rental near Oxford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Will you come out to St Clement's?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Do you have insurance?
Yes, we are fully insured.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with pictures if you can, and we will quote. We will tell you if anything on it isn’t a sealant job.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Should I wait before resealing?
Any seal that’s leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
How do I get a quote for new build mastic in St Clement's?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Broken tiles or a split tray
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Signs you need new build mastic in St Clement's
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracked sealant shows up.
Any of these means the joints need attention:
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
For new homes near Oxford station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- How much experience the applicator has
- What insurance they hold
- How the surfaces are prepared before sealing
- How the colour is chosen
Can I do it myself?
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 do try it yourself, take your time over the 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.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours in a single home. In a smaller place like St Clement's, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
