New build mastic in Walton Hall, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you have beads laid onto grit and dust from the build and cracked sealant around new window and door frames, we can put it right, on kitchens, show homes and windows & doors alike.
Around Walton Hall, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, in Walton Hall and everywhere else we cover.

Your questions about new build mastic in Walton Hall
Is Walton Hall within the area you cover?
Yes. Walton Hall is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Bow Brickhill station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. We will confirm how long when we quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours in a single home, depending on the size of the job. Somewhere as small as Walton Hall, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Mention any tricky access

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Why act early in Walton Hall
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. Older cottages and farmhouses around Walton Hall can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
