The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job normally takes a few hours in a single home, and we tell you how long to leave it before we go. Somewhere like Weston Otmoor needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before

New build mastic for homes and businesses in Weston Otmoor
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you’re dealing with cracks appearing as a new home settles and untidy sealant flagged on a snagging list, we can put it right, on plot handovers, show homes and kitchens alike.
Somewhere as small as Weston Otmoor, 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.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Quotes for new build mastic in Weston Otmoor
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- Mould in or behind the old joints
- Whether the work is at height
- Any working-time requirements on site
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
To help us quote quickly, please include:
- Whether it has been sealed before
- How we’d reach the joints
- Where the property is
- A few photos by email, if you can
For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before any work starts.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
- Photograph failed sealant before it’s redone
- Resist patching a failed seal with a tube from the DIY shop
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
Questions from Weston Otmoor
Will you come out to Weston Otmoor?
Yes, Weston Otmoor is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do new build mastic in Weston Otmoor?
Yes, Weston Otmoor is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Do you have insurance?
Yes. We’re fully insured.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
How much does new build mastic cost in Weston Otmoor?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can I do it myself?
You can, for simple jobs. 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.
What happens if it’s left?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. In a small place like Weston Otmoor, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
- Disputes or warranty claims with your builder
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
