How we handle new build mastic in Cuddesdon
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on skirting & floors, show homes and plot handovers, and people most often call us about sealant that never bonded to the surface and internal frame sealant that has split.
In a village or hamlet like Cuddesdon, 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.
There’s a 12-month guarantee on every job, large or small.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What affects the quote in Cuddesdon
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Which sealant suits the joint
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- The address or postcode of the job
- How many joints, rooms or windows are involved
- How we’d reach the joints
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
What we can’t put right
We won’t take on work that will not last, so these are the limits:
- A tray or bath that isn’t properly supported, until it’s fixed
- Settlement cracks that need a surveyor
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Why act early in Cuddesdon
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. In a small place like Cuddesdon, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Why us?
- Rated 4.9 stars on Google
- Full insurance on every job
- Sanitary silicone with an anti-fungal additive in wet areas
- 20+ years of sealant experience

Your questions about new build mastic in Cuddesdon
Can you do new build mastic in Cuddesdon?
Yes. We work across London and the South East, and Cuddesdon is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
What guarantee comes with new build mastic in Cuddesdon?
All our work, in Cuddesdon and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long should I leave it?
Cure times vary by product. We tell you how long to leave it before we go.
Do you work through snagging lists?
Yes. Send the list and a few photos of the sealant items and we’ll give you a quote. We will flag anything that needs another trade.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.

What we do, step by step

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.
- We cut out every bit of the failed or messy sealant.
- 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.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Signs you need new build mastic in Cuddesdon
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry.
The problems people generally mention when they call are:
- Shower seals failing in the first year or two
- Sealant work across a run of new homes
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
Whether the job is in Cuddesdon itself or nearby, the right material for each joint matters as much as a neat finish.

- Is VAT in the price?
