New build mastic for homes and businesses in Much Hadham
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have gaps opening as the house dries out and settles and sealant work across a run of new homes, we can help, on windows & doors, bathrooms & en suites and show homes alike.
Work in a small place like Much Hadham just needs the journey and access planning, and the work itself is the same as on any site.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

What new build mastic looks like in Much Hadham

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Much Hadham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What happens on the day
The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours in a single home. Somewhere as small as Much Hadham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit

- Tell us about any previous sealing or DIY attempts

Advice
FAQs for Much Hadham
I let a flat near Bishops Stortford station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Much Hadham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. If it isn’t resolved, we’ll cut it out and reseal it.
How long does new build mastic take?
Most jobs take anything from a few hours to several days, depending on the number of plots, including the preparation. We will confirm how long when we quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Where are you based?
We work from Crawley. Our applicators cover Much Hadham.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Look at the sealant regularly in the first couple of years
- Don’t seal over failed sealant yourself
- Use the extractor fan every time you shower
- Don’t wait for the house to settle if water is getting through
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.
Joints and surfaces we work on

When to call us in Much Hadham
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Keep an eye out for any of the following:
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
For new homes near Bishops Stortford station, it’s worth checking the sealant early, while snags are still fresh.
