New build mastic for homes and businesses in East Shefford
We work in new homes and on new-build sites across East Shefford. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on kitchens, show homes and windows & doors, and the jobs we see most are sealant work across a run of new homes and gaps behind new kitchen upstands.
Somewhere as small as East Shefford, 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.
Every job comes with our 12-month guarantee.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Avoid running a DIY bead over the old one
- Record problems with dated pictures
- Wipe joints with warm soapy water
- Check bath and shower seals every few months as the house settles
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
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.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Your questions about new build mastic in East Shefford
Can you help a landlord with a rental near Kintbury station?

Is East Shefford in your area for new build mastic?
Yes, East Shefford is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.
Do you work through snagging lists?
Yes. Send it with pictures and we’ll quote for the sealant items. If something isn’t sealant, we’ll say so.
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.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. Somewhere like East Shefford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Plot handovers
Developers can send the plot schedule and specification for a quote. Sealant work across the plot is covered.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Why act early in East Shefford
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. In a small place like East Shefford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
