New build mastic in Tilgate
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Typical jobs include leaking shower tray seals in a new home and sealant applied over dusty or wet surfaces, across show homes, plot handovers and skirting & floors.
In and around Tilgate, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal cannot. If you’re unsure which you have, call 0345 464 0079 or drop us an email with pictures and we’ll tell you. In a smaller place like Tilgate, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What new build mastic looks like in Tilgate
Tilgate is part of Crawley, one of the post-war new towns. Newer neighbourhoods have been added to Crawley over the years, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Crawley station, it’s worth checking the sealant early, while snags are still fresh.

What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. For a job in Tilgate, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.

- Keep children and pets away from the work area

What sealant work cannot fix
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Signs you need new build mastic in Tilgate
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
These are the problems we are asked about most:
- Leaking shower tray seals in a new home
- Messy sealant that spoils new finishes
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
In and around Tilgate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Whether the sealant suits the joint
- Which colour the sealant will be
- What guarantee comes with the work
- Is the old sealant removed completely?
Tilgate: your questions answered
I let a flat near Crawley station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Tilgate?
Yes, Tilgate is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
