New build mastic for homes and businesses in Downham
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. We work on plot handovers, skirting & floors and bathrooms & en suites, and common reasons people get in touch are internal frame sealant that has split and gaps opening as the house dries out and settles.
Work in a small place like Downham just needs the journey and access planning, and the work itself is the same as on any site.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Downham
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
The most common problems we see are:
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Wickford station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- How hidden problems are handled
- What insurance they hold
- When the joint can take water or movement
- What preparation is included
How it works
The work is kept neat and contained to the area we’re working on. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Somewhere as small as Downham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Downham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
Why us?
- Full insurance on every job
- Approved under the ARBOMaster scheme
- Sanitary silicone with an anti-fungal additive in wet areas
- Any old sealant cut out fully, not covered over

Common questions in Downham
Is Downham within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Downham for new build mastic?
Yes. Our work covers London and the South East, and Downham is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. We’ll confirm how long when we quote.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job.
Different surfaces, different methods
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
