How we handle new build mastic in Lower Denford
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for shower seals failing in the first year or two and worktop and upstand sealant coming away, across skirting & floors, plot handovers and kitchens.
Work in a small place like Lower Denford just needs the journey and access planning, and once on site, the job is the same as anywhere.
Every job comes with our 12-month guarantee, wherever you are in West Berkshire.

Do you work through snagging lists?
Yes. Send it with photos and we will quote for the sealant items. If something is not sealant, we will say so.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Common problems we fix in Lower Denford
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
Common reasons people contact us are:
- Messy sealant that spoils new finishes
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Gaps between new skirting and floors

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
- Do not wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home, including the tidy-up. Somewhere as small as Lower Denford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Tell us about any water getting in
