DIY versus a professional finish
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. All the old material has to come out first.
The difference is mostly in the preparation and the 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.
New build mastic for homes and businesses in Nyewood
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 sealant actually sticks rather than sitting on a layer of grit. Common call-outs are for shower seals failing in the first year or two and gaps opening as the house dries out and settles, across bathrooms & en suites, show homes and skirting & floors.
Work in a small place like Nyewood just needs the journey and access planning, and the work itself is the same as on any site.
We stand behind the work with a 12-month guarantee.

Surface by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

Nyewood questions
I let a flat near Petersfield station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Nyewood within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Are you insured?
Yes. Mr Mastic is fully insured.
Where are you based?
We work from Crawley. Our applicators cover Nyewood, along with the rest of our area.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
New build mastic in Nyewood: local notes

Work for landlords, hotels and businesses
If you manage several properties in or around Nyewood, several properties can be quoted together. Just tell us the addresses and what each one needs.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you are unsure which you have, phone 0345 464 0079 or email us with photos and we’ll tell you. Around Nyewood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.

How the visit works
At the end, we look at the finished work together. The visit itself usually takes a few hours in a single home, depending on how much there is to do. In a small place like Nyewood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
