What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Dunton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- 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.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Advice
About our new build mastic in Dunton
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. Typical jobs include worktop and upstand sealant coming away and gaps opening as the house dries out and settles, on bathrooms & en suites, plot handovers and show homes.
Older homes in small places like Dunton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether the work is at height
- Which sealant suits the joint
- When we can work, for business premises
- How many rooms, windows or areas are involved
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the property is
- Pictures of the joints, sent by email
- If someone has resealed it before
- The rough size of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or send us an email.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Dunton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why book with us
- White, clear, grey or coloured to suit, where the product allows

Common problems we fix in Dunton
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
The problems people generally mention when they call include:
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
For jobs in and around Dunton, choosing the right material for each joint is as important as a tidy finish.

Questions from Dunton
Do you cover smaller places like Dunton?
Yes, Dunton is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What guarantee comes with new build mastic in Dunton?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Buckinghamshire.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Why has my new-build shower seal failed already?
It’s common, and there are usually 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. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items, and we’ll quote. We’ll flag anything that needs another trade.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Different surfaces, different methods
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
