FAQs for Sulhamstead
Can you help a landlord with a rental near Theale station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Sulhamstead?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can I do it myself?
That depends on the joint. 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.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
New build mastic in Sulhamstead, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on skirting & floors, bathrooms & en suites and windows & doors, and common reasons people get in touch are smeared, uneven beads picked up at snagging and frame joints opening as the plaster dries.
In a village or hamlet like Sulhamstead, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in Sulhamstead
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Older cottages and farmhouses around Sulhamstead can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why us?
- More than 20 years in sealant work

When to call us in Sulhamstead
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The problems people generally mention when they call include:
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
- Joints pulling apart as timber shrinks
- Shower seals failing in the first year or two
Around Sulhamstead, as everywhere, new build mastic is only as good as the preparation behind it.

Aftercare tips
A little care helps the new joints last. Our advice:
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
