Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Wexham Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Why book with us
- Experience in homes, commercial sites and hotels
- Anti-fungal sanitary silicone in wet areas

- Sealant colour chosen to suit

About our new build mastic in Wexham Street
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We are often asked to deal with shower seals failing in the first year or two and gaps opening as the house dries out and settles, across kitchens, plot handovers and bathrooms & en suites.
Around Wexham Street, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What affects the quote in Wexham Street
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When to call us in Wexham Street
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry.
Most people get in touch when they notice one of these:
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Slough station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Whether they’re fully insured
- What happens if the job turns out different
- When the joint can take water or movement
- Whether all the old sealant comes out first
FAQs for Wexham Street

Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Where are you based?

When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
