How we handle new build mastic in Great Rollright
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. We work on show homes, kitchens and windows & doors, and people most often call us about smeared, uneven beads picked up at snagging and gaps opening as the house dries out and settles.
Somewhere as small as Great Rollright, 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.
All of our work is guaranteed for twelve months.

Signs you need new build mastic in Great Rollright
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
Signs it’s time to call us include:
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
- Gaps opening as the house dries out and settles
- Sealant work across a run of new homes
Whether the job is in Great Rollright itself or nearby, the right material for each joint matters as much as a neat finish.

Questions from Great Rollright
What guarantee comes with new build mastic in Great Rollright?
All our work, in Great Rollright and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Great Rollright for new build mastic?
Yes, Great Rollright is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
What colour sealant will you use?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish and agree it with you.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early. Poor preparation at handover adds to it.
Landlord and commercial work in Great Rollright

Landlords and agents in Great Rollright can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors as agreed.
Looking after it afterwards
Aftercare is simple:
- Raise failed sealant with the developer while you are covered
- Clean sealant with mild detergent, not abrasives
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with right away
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the number of plots from start to finish.

Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.

- Tell us about any water getting in
- Tell us if parking is tricky

Advice
DIY sealant or a professional job?
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.
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 fails, we can still redo it.

What else we do in Great Rollright
Why it’s worth doing now in Great Rollright
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a small place like Great Rollright, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
