FAQs for Upton
Can you do new build mastic in Upton?
Yes. We work across London and the South East, and Upton is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Will you come out to Upton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we’ll give you a quote.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items and we will give you a quote. We’ll tell you if anything on it isn’t a sealant job.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
About our new build mastic in Upton
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, show homes and bathrooms & en suites, and the jobs we see most are cracked caulk along new skirting and second-fix sealing on new plots.
If you’ve bought a new home in or near Upton, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Honest limits
In fairness, there are a few things sealant will not fix:
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath

How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours in a single home in most cases. Parking around Upton is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We’ll plan around viewing times.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Common problems we fix in Upton
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Common reasons people contact us are:
- Gaps opening as the house dries out and settles
- Plot mastic for developers ahead of handover
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
In and around Upton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
