How we handle new build mastic in Holbrook
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you’re dealing with plot mastic for developers ahead of handover and leaking shower tray seals in a new home, we can put it right.
Work in a small place like Holbrook just needs the journey and access planning, and once on site, the job is the same as anywhere.
Every job is covered by a one-year guarantee.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. In a small place like Holbrook, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- 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.
How to prepare
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Your questions about new build mastic in Holbrook
Do you cover smaller places like Holbrook?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Warnham station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
Aftercare tips
Looking after new joints is easy:
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.

What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Access and height
- The number of rooms or windows
- Whether there’s mould to deal with
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- The type of property
- The address or postcode of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or drop us an email.
How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
New build mastic in Holbrook: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Holbrook, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Warnham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why it’s worth doing now in Holbrook
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In a small place like Holbrook, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- An ARBOMaster approved applicator
- Trusted Arbo and Everbuild sealants
- Old sealant always removed completely
Landlord and commercial work in Holbrook
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.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we will tell you before we start. It will not solve:
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
