About our new build mastic in Moulsoe
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on plot handovers, show homes and skirting & floors, and the jobs we see most are sealant applied over dusty or wet surfaces and new-build shower sealant that has already split.
For a small place like Moulsoe, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Big or small, you get the same 12-month guarantee in Moulsoe and across Milton Keynes.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Moulsoe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

What new build mastic looks like in Moulsoe
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Woburn Sands station, the sealant around baths, showers and frames is worth checking in the first year or two.

Near you in Moulsoe

A little further out are Milton Keynes University Hospital (3.7 miles south-west) and Midsummer Place (3.6 miles south-west). For a walk, there’s Willen Lake.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
FAQs for Moulsoe

What does new build mastic cost?
There’s no set price, as it 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.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved and we will quote.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early. Rushed application on dusty surfaces makes it worse.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. Somewhere as small as Moulsoe, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Move anything stored near the joints
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Advice
Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Raise failed sealant with the developer while you are covered
- Avoid running a DIY bead over the old one
- Clean sealant with mild detergent, not abrasives
- Do not wait for the house to settle if water is getting through
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
