About our new build mastic in Clewer
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on show homes, plot handovers and windows & doors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and worktop and upstand sealant coming away.
In smaller places like Clewer, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
Whatever the size of the job, it’s backed by our one-year guarantee.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Questions from Clewer
Can you help a landlord with a rental near Windsor & Eton Central station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Clewer?
Yes, Clewer is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What information do you need?
Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, large or small.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Report sealant problems to your builder during the snagging period
- Do not wait for the house to settle if water is getting through
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Why act early in Clewer
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In an older home around Clewer, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

How the visit works
The work is kept neat and contained to the area we’re working on. The job generally takes a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. A visit to Clewer is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Mention any tricky access
- Tell us about any water getting in
- Tell us if parking is tricky

Advice
What we are called out for in Clewer
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
People generally contact us after spotting something like this:
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Windsor & Eton Central station, the sealant around baths, showers and frames is worth checking in the first year or two.
