New build mastic in Booker, done properly
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that’s letting water through needs doing now. If you have sealant applied over dusty or wet surfaces and gaps behind new kitchen upstands, we can put it right, on plot handovers, show homes and kitchens alike.
If you’ve bought a new home in or near Booker, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Your job is guaranteed for a year, as with all our work.

How do I get a quote for new build mastic in Booker?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or email us and let us know what needs doing and where.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Do you work for developers?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved for a clear quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why it’s worth doing now in Booker
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Homes in smaller places like Booker can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

When to call us in Booker
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
Common reasons people contact us are:
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
In and around Booker, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
- Broken tiles or a split tray
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Bathrooms & en suites

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a smaller place like Booker, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.
