How the job changes by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.
About our new build mastic in Munstead Heath
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for second-fix sealing on new plots and worktop and upstand sealant coming away, across plot handovers, windows & doors and show homes.
Around Munstead Heath, 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.
You get a one-year guarantee, the same in Munstead Heath as everywhere else we work.

Munstead Heath: your questions answered
Do you cover Munstead Heath for new build mastic?
Yes, Munstead Heath is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Will you come out to Munstead Heath?
Yes. Munstead Heath 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.
How long will you be here?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. We’ll confirm how long when we quote.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Munstead Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Joints and finishes in Munstead Heath homes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours in a single home. Somewhere as small as Munstead Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
