About our new build mastic in Aston

Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We are often asked to deal with leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall, across show homes, bathrooms & en suites and skirting & floors.

In a village or hamlet like Aston, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

All our work comes with a one-year guarantee, wherever you are in Oxfordshire.

Different surfaces, different methods

Skirting and floors

New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.

Plot handovers

Developers can send the plot schedule and specification and we’ll quote. We seal bathrooms, kitchens, frames and floors as agreed.

What we do, step by step

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. For a village or hamlet like Aston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  3. Joints are vacuumed and cleaned of building dust.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. We tool every joint neatly and tell you when each area can be used.

Before we arrive

  • Mention any tricky access
  • Plan for the work area to be out of bounds to pets and children
  • For business premises, tell us about site rules or sign-in

Advice

Landlords, agents and businesses in Aston

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Clean sealant with mild detergent, not abrasives
  • Keep pictures and emails about snagging items
  • Act quickly if a seal starts to leak
  • Open a window or run the fan after bathing

Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day.

If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Common problems we fix in Aston

Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.

People usually contact us after spotting one of these:

  • Internal frame sealant that has split
  • Plot mastic for developers ahead of handover
  • New-build shower sealant that has already split
  • Worktop and upstand sealant coming away

For jobs in and around Aston, choosing the right material for each joint is as important as a tidy finish.

Our hiring checklist

What we cannot put right

It helps to know what we cannot do:

  • A tray or bath that isn’t properly supported, until it’s fixed
  • Leaks from pipes, valves or wastes, which need a plumber
  • Deciding who is responsible under a builder’s warranty

If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

What we seal

  • Bathrooms & en suites
  • Plot handovers
  • Kitchens
  • Windows & doors
  • Show homes
  • Skirting & floors

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

FAQs for Aston

Will you come out to Aston?

Yes. Aston is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is there a guarantee on new build mastic in Aston?

Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

Are you an approved applicator?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Who should fix failed sealant in a new build?

Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we are happy to quote.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
