Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We are often asked to deal with cracked sealant around new window and door frames and skirting joints opening in the first winter, on skirting & floors, bathrooms & en suites and windows & doors.
If you’ve bought a new home in or near Lawrence Hill, 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.

How we quote for new build mastic
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- Mould in or behind the old joints
- Any working-time requirements on site
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Roughly how big the job is
- The type of property
For a quote, ring 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
Honest limits
To be straight with you, some problems need a different trade:
- Cracked trays, tiles or worktops
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

What else we do in Lawrence Hill
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
- Ventilate bathrooms well, especially in the first year
- 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.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.

Joints and finishes in Lawrence Hill homes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Bracknell, which Lawrence Hill is part of, is one of England’s post-war new towns. Bracknell has kept growing, with newer neighbourhoods added to the original town. Older homes need their sealant and floor joints renewing, newer ones checking at snagging.

What the job involves on each 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.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Landlord and commercial work in Lawrence Hill
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
We also work for property managers and facilities teams in Lawrence Hill and across Bracknell Forest. We can quote a run of properties together, and we’re fully insured for the work.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a job in Lawrence Hill, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
