New build mastic for homes and businesses in Lathbury
Across Lathbury, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. Typical jobs include smeared, uneven beads picked up at snagging and sealant that never bonded to the surface, across bathrooms & en suites, kitchens and skirting & floors.
Work in a small place like Lathbury just needs the journey and access planning, and once on site, the job is the same as anywhere.
Whatever the size of the job, it’s backed by our one-year guarantee in Lathbury and across Milton Keynes.

Common problems we fix in Lathbury
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Keep an eye out for any of the following:
- Second-fix sealing on new plots
- Cracked caulk along new skirting
- Internal frame sealant that has split
- Cracks appearing as a new home settles
If you’ve bought a new home near Wolverton station, the sealant around baths, showers and frames is worth checking in the first year or two.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Lathbury, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Mention if the joints have been sealed before

FAQs for Lathbury
Do you work for landlords with property near Wolverton station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is Lathbury within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you an approved applicator?

Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Should I try DIY first?
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.
How long does the job take?
Typically it takes a few hours in a single home. Larger jobs naturally take longer, and we will say how long yours will take.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Get a leaking seal dealt with right away
- Put sealant faults on your snagging list early
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
When it is not the sealant
A few problems are outside what sealant work can do:
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
- Structural cracks in walls or ceilings
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Around Lathbury, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
