Woodcote questions
Do you work for landlords with property near Reedham (London) station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Woodcote in your area for new build mastic?
Yes, Woodcote is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots. We will confirm how long when we quote.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
New build mastic for homes and businesses in Woodcote
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have plot mastic for developers ahead of handover and kitchen sealant that has pulled off the wall, we can put it right, on plot handovers, windows & doors and kitchens alike.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Woodcote as anywhere.
Big or small, you get the same 12-month guarantee in Woodcote and across Greater London.

New build mastic in Woodcote: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Woodcote can be tricky for parking: let us know about parking bays, permits or a driveway.

Common problems we fix in Woodcote
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Reedham (London) station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Whether the sealant suits the joint
- Whether VAT is included
- How the colour is chosen
- What the cure time is
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
How we quote for new build mastic
You’ll get a clear quote before any work starts. It takes into account:
- Whether the work is at height
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The number and length of the joints
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
Helping us quote
When you contact us, it’s useful to know:
- If someone has resealed it before
- A few pictures by email, if you can
- Where the property is
- The type of property
We do not publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Don’t wait for the house to settle if water is getting through
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Woodcote. It helps if you can point us to a visitor permit or a bay close to the door.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on
Getting a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
