How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It usually takes a few hours in a single home. A visit to Tongham is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit

Advice
New build mastic in Tongham, done properly
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 gets into the floor or walls. We work on kitchens, show homes and plot handovers, and the jobs we see most are worktop and upstand sealant coming away and beads laid onto grit and dust from the build.
For a new home in or near Tongham, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Your questions about new build mastic in Tongham
Can you do new build mastic in Tongham?
Yes. Our work covers London and the South East, and Tongham is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is Tongham within the area you cover?
Yes. Tongham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
How long does new build mastic take?
Typically it takes a few hours in a single home. Bigger jobs take longer, and we’ll tell you how long to expect.
Are you insured?
Yes. We are fully insured.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
How to look after the new joints
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
- Look at the sealant regularly in the first couple of years
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Early snagging is easier snagging. Small faults turn into leaks if left.
Quotes for new build mastic in Tongham
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- Whether there’s mould to deal with
- Working hours on commercial sites

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- Any access issues, like height or stairs
- A few pictures by email, if you can

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Why it’s worth doing now in Tongham
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Tongham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Most people get in touch after spotting one of these:
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
- Gaps opening as the house dries out and settles
- Internal frame sealant that has split
If you’ve bought a new home near Ash station, the sealant around baths, showers and frames is worth checking in the first year or two.
