How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
To help us quote quickly, please include:
- Roughly how big the job is
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
New build mastic in Finchampstead, done properly
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. If you’re dealing with messy sealant that spoils new finishes and leaking shower tray seals in a new home, we can put it right, on plot handovers, show homes and kitchens alike.
Somewhere as small as Finchampstead, 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.
There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Finchampstead
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Finchampstead, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Deciding who is responsible under a builder’s warranty
- A tray or bath that is not properly supported, until it’s fixed
- Settlement cracks that need a surveyor
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Put sealant faults on your snagging list early
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Questions from Finchampstead
Do you cover Finchampstead for new build mastic?
Yes. We work across London and the South East, and Finchampstead is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you work for landlords with property near Crowthorne station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
How much does new build mastic cost in Finchampstead?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email and let us know what needs doing and where.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal 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.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. In a small place like Finchampstead, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Mention any tricky access

Advice
When to call us in Finchampstead
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Signs it’s time to call us include:
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
- Skirting joints opening in the first winter
- Leaking shower tray seals in a new home
If you’ve bought a new home near Crowthorne station, the sealant around baths, showers and frames is worth checking in the first year or two.
