New build mastic for homes and businesses in Englefield
Across Englefield, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. Typical jobs include second-fix sealing on new plots and internal frame sealant that has split, across show homes, bathrooms & en suites and plot handovers.
For a small place like Englefield, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Surface by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Letting agents and landlords in Englefield can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
When to call us in Englefield
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Keep an eye out for these signs:
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
- Internal frame sealant that has split
Around Englefield, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book

Common questions in Englefield
Do you work for landlords with property near Theale station?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you do new build mastic in Englefield?
Yes. We work across London and the South East, and Englefield is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Englefield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Englefield, 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.
- Old sealant is cut out and the joints cleaned.
- 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.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job.
Advice
When something else is needed
It helps to know what we cannot do:
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
