What we’re called out for in Datchet
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
These are the problems we are asked about most:
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
For new homes near Datchet station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Is VAT in the price?
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- What product goes in the joint
New build mastic for homes and businesses in Datchet
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you are dealing with sealant work across a run of new homes and cracks appearing as a new home settles, we can help, on skirting & floors, plot handovers and bathrooms & en suites alike.
For a new home in or near Datchet, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Why act early in Datchet
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Around Datchet, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually 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 Datchet, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Honest limits
To be straight with you, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
