About our new build mastic in Ash
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you are dealing with sealant work across a run of new homes and shower seals failing in the first year or two, we can put it right, on bathrooms & en suites, plot handovers and kitchens alike.
If you’ve bought a new home in or near Ash, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Record problems with dated photos
- Follow the cure time we give you
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you’re covered
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Your questions about new build mastic in Ash
Will you come out to Ash?
Yes, Ash is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Sandwich station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Should I wait before resealing?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What affects the cost of new build mastic
We do not publish a price list. What we look at:
- Mould in or behind the old joints
- The number of rooms or windows
- The product the joint needs
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
- Where the property is
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or send us an email with the details and send pictures if you have them.
What we do, step by step
At the end, we look at the finished work together. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. For a job in Ash, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- 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.
