New build mastic in Kingston Blount, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on bathrooms & en suites, kitchens and windows & doors, and common reasons people get in touch are messy sealant that spoils new finishes and gaps behind new kitchen upstands.
For a small place like Kingston Blount, the journey and access are planned in advance, and the work itself is the same as on any site.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. Somewhere like Kingston Blount needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Why it’s worth doing now in Kingston Blount
A hairline gap at a skirting can wait, but a leaking seal cannot. If you are unsure which you have, phone 0345 464 0079 or email us with pictures and we’ll give you a straight answer. Around Kingston Blount, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

Do you need new build mastic in Kingston Blount?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
In and around Kingston Blount, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Kingston Blount questions
Will you come out to Kingston Blount?
Yes. Kingston Blount is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Princes Risborough station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early. Poor preparation at handover adds to it.
What colour sealant will you use?
White and clear are the most common, but other colours are available. We match the colour to the finish and agree it with you.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
Aftercare tips
Looking after new joints is easy:
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Act quickly if a seal starts to leak
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
