New build mastic in Waltham, done properly
Across Waltham, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. Typical jobs include new-build shower sealant that has already split and plot mastic for developers ahead of handover, across windows & doors, show homes and skirting & floors.
In a village or hamlet like Waltham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a one-year guarantee.

Why act early in Waltham
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Waltham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- You choose the colour before work begins
- Approved under the ARBOMaster scheme
- A 12-month guarantee on all work

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. Somewhere as small as Waltham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Your questions about new build mastic in Waltham
I let a flat near Chilham station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Will you come out to Waltham?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
How do I get a quote for new build mastic in Waltham?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we will tell you how long to expect.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What affects the quote in Waltham
Some jobs are bigger than they look, and some smaller. The main factors:
- How much there is to do
- The old material and how stubborn it is
- Mould in or behind the old joints
- The number of rooms or windows
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Roughly how big the job is
- Photos by email, if that’s easy
To get a quote, call 0345 464 0079 or email us with the location and a short description of the problem. We will send you a clear quote before any work starts.
How to look after the new joints
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
For landlords and businesses
We also work for property managers and facilities teams in Waltham and across Kent. We can quote a run of properties together.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
