New build mastic in Grayshott, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for kitchen sealant that has pulled off the wall and cracks appearing as a new home settles, on plot handovers, bathrooms & en suites and windows & doors.
In smaller places like Grayshott, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
Looking after new joints is easy:
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
- Record problems with dated photos
- Wipe joints with warm soapy water
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Structural cracks in walls or ceilings
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Common problems we fix in Grayshott
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
The problems people usually mention when they call are:
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
- Worktop and upstand sealant coming away
For new homes near Haslemere station, it’s worth checking the sealant early, while snags are still fresh.

Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
FAQs for Grayshott
Can you help a landlord with a rental near Haslemere station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is Grayshott in your area for new build mastic?
Yes, Grayshott is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Why has my new-build shower seal failed already?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. If it is not resolved, we can reseal it properly.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. In a smaller place like Grayshott, 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, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
