Is Farnham Royal within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long does new build mastic take?
That depends on how much there is to do, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.
Where are you based?

About our new build mastic in Farnham Royal
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you’re dealing with plot mastic for developers ahead of handover and cracked sealant around new window and door frames, we can help, whatever the surface.
Somewhere as small as Farnham Royal, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
There’s a 12-month guarantee on every job, large or small.

Common problems we fix in Farnham Royal
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
The most common problems we see are:
- Sealant work across a run of new homes
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
For new homes near Burnham station, it’s worth checking the sealant early, while snags are still fresh.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Act quickly if a seal starts to leak
- Do not seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
- Record problems with dated photos
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Around Farnham Royal, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
