New build mastic in Filchampstead

How we handle new build mastic in Filchampstead

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We’re often asked to deal with frame joints opening as the plaster dries and sealant that never bonded to the surface, on plot handovers, windows & doors and show homes.

Around Filchampstead, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

Each job carries a 12-month guarantee.

How it works

We keep the work tidy and contained to the area we are working on. Expect the work to take anything from a few hours to several days, depending on the number of plots. Somewhere like Filchampstead needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you’re given the cure time.

How to prepare

  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in
  • Clear items away from the joints we’re working on

Advice

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Don’t seal over failed sealant yourself
  • Put sealant faults on your snagging list early
  • Follow the cure time we give you
  • Avoid scourers and strong chemicals on sealant

Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.

Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.

Common problems we fix in Filchampstead

Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.

The most common problems we see are:

  • Leaking shower tray seals in a new home
  • Cracks appearing as a new home settles
  • Frame joints opening as the plaster dries
  • Sealant that never bonded to the surface

In and around Filchampstead, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What your quote should include

  • Are they insured?
  • How long the guarantee is
  • Which colour the sealant will be
  • When the joint can take water or movement

What the job involves on each surface

Show homes

Kitchens

Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.

Joints and finishes in Filchampstead homes

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For new homes near Oxford station, it’s worth checking the sealant early, while snags are still fresh.

DIY versus a professional finish

If you’re 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 fails, we can still redo it.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

For landlords and businesses

We also work for property managers and facilities teams. We can quote a run of properties together.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.

What sealant work cannot fix

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Deciding who is responsible under a builder’s warranty
  • A tray or bath that is not properly supported, until it’s fixed
  • Settlement cracks that need a surveyor

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
