How we handle new build mastic in Long Sutton
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation, because that is what rushed new-build sealant usually lacks. Common call-outs are for leaking shower tray seals in a new home and plot mastic for developers ahead of handover, on kitchens, show homes and skirting & floors.
Somewhere as small as Long Sutton, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
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.
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Long Sutton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are 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 doesn’t work out, we can still put it right.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
- Record problems with dated photos
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
What affects the quote in Long Sutton
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Any mould that needs treating
- How easy the joints are to reach
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- The problem you’ve noticed
- Any access issues, like height or stairs
- If someone has resealed it before
- Where the property is
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
