About our new build mastic in Shirley Oaks
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We work on bathrooms & en suites, kitchens and plot handovers, and the jobs we see most are smeared, uneven beads picked up at snagging and plot mastic for developers ahead of handover.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
Every job is covered by our 12-month guarantee, wherever you are in Greater London.

Shirley Oaks: your questions answered
Do you cover Shirley Oaks for new build mastic?
Yes, Shirley Oaks is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
I let a flat near Elmers End station. Can you help?
Yes, rental work is part of what we do. You can ring 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.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can you work from my snagging list?
Yes. Send the list and a few pictures of the sealant items and we’ll give you a quote. We will flag anything that needs another trade.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
How long does new build mastic take?
A typical job takes a few hours in a single home, including preparation and clearing up. We’ll confirm how long when we quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we can reseal it properly.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
How it works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. For a job in Shirley Oaks, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

Advice
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Common problems we fix in Shirley Oaks
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
People usually contact us after spotting one of these:
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
For new homes near Elmers End station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- What the cure time is
- Whether the sealant suits the joint
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Clean sealant with mild detergent, not abrasives
- Record problems with dated photos
- Put sealant faults on your snagging list early
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Why it’s worth doing now in Shirley Oaks
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a flat in Shirley Oaks, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
