New build mastic for homes and businesses in Deadwater
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 windows & doors, bathrooms & en suites and kitchens, and common reasons people get in touch are shower seals failing in the first year or two and beads laid onto grit and dust from the build.
Homes around Deadwater range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
There’s a 12-month guarantee on every job.

How we quote for new build mastic
For a quick quote, just ask. The main things that affect it are:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- When we can work, for business premises
- The old material and how stubborn it is
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
To help us quote quickly, let us know:
- Where the property is
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Whether it has been sealed before
We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or drop us an email and describe the job, and pictures are welcome.
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 chosen for how the joint moves and where it is.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. In a smaller place like Deadwater, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- 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.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Mention if the joints have been sealed before

Advice
Surface by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Deadwater questions
Do you cover smaller places like Deadwater?
Yes. Deadwater is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Liphook station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
Are you insured?
Yes, we’re fully insured.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.

What else we do in Deadwater
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Wait for the cure time before using a resealed shower
- Avoid running a DIY bead over the old one
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
What new build mastic looks like in Deadwater
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Liphook station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Deadwater, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
A hairline gap at a skirting can wait, but a leaking seal can’t. If you’re unsure which you have, call 0345 464 0079 or drop us an email with photos and we’ll tell you. Around Deadwater, 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.
