We work on show homes, skirting & floors and plot handovers, and common reasons people get in touch are plot mastic for developers ahead of handover and messy sealant that spoils new finishes.

Quotes for new build mastic in Walberton
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Whether there’s mould to deal with
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. Your quote takes all of that into account.
What to tell us for a quote
To make quoting easier, let us know:
- If someone has resealed it before
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- The problem you’ve noticed
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Walberton questions
Do you cover smaller places like Walberton?
Yes, Walberton is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do new build mastic in Walberton?
Yes. We work across London and the South East, and Walberton is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
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.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
What do you put in the joint?
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 explain our choice.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.

How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Plot handovers
Developers can send the plot schedule and specification for a quote. Sealant work across the plot is covered.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. Somewhere as small as Walberton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Advice
Landlords, agents and businesses in Walberton
Letting agents and landlords in Walberton can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Signs you need new build mastic in Walberton
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Keep an eye out for these signs:
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
If you’ve bought a new home near Barnham station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Is VAT in the price?
- Whether all the old sealant comes out first
- What insurance they hold
- Whether you can choose the colour
