Questions from Moorhouse Bank
Is Moorhouse Bank in your area for new build mastic?
Yes, Moorhouse Bank is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Hurst Green station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Are you fully insured?
Yes. We are fully insured.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.
New build mastic for homes and businesses in Moorhouse Bank
Across Moorhouse Bank, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. If you have untidy sealant flagged on a snagging list and worktop and upstand sealant coming away, we can help.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. 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.
What affects the cost of new build mastic
We don’t publish a price list. The quote depends on:
- Working hours on commercial sites
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- The type of sealant required
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- The rough size of the job
- Whether it’s a home or a business
- The address or postcode of the job
- Pictures of the joints, sent by email
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal

- Skirting & floors

New build mastic in Moorhouse Bank: local notes

As a London address, Moorhouse Bank can be tricky for parking: let us know about parking bays, permits or a driveway.

What we’re called out for in Moorhouse Bank
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
For new homes near Hurst Green station, it’s worth checking the sealant early, while snags are still fresh.
