How we handle new build mastic in Ascott d'Oyley

New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you are dealing with skirting joints opening in the first winter and gaps behind new kitchen upstands, we can put it right, whatever the surface.

Work in a small place like Ascott d'Oyley just needs the journey and access planning, and the work itself is the same as on any site.

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

When to call us in Ascott d'Oyley

The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.

The problems people usually mention when they call include:

  • Internal frame sealant that has split
  • Plot mastic for developers ahead of handover
  • Joints pulling apart as timber shrinks
  • Leaking shower tray seals in a new home

If you’ve bought a new home near Ascott-Under-Wychwood station, the sealant around baths, showers and frames is worth checking in the first year or two.

10 questions to ask before you book

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Why it’s worth doing now in Ascott d'Oyley

Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, call 0345 464 0079 or email us with pictures and we’ll tell you. Older cottages and farmhouses around Ascott d'Oyley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

When it isn’t the sealant

We’ll always be straight with you, so here’s what sealant cannot fix:

  • Movement caused by a poorly fitted tray or bath
  • Deciding who is responsible under a builder’s warranty
  • Plumbing faults behind the sealant

If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Ascott d'Oyley: your questions answered

Is Ascott d'Oyley in your area for new build mastic?

Yes, Ascott d'Oyley is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.

Will you come out to Ascott d'Oyley?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

How long does new build mastic take?

Most jobs take a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator.

Can tenants book the work?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Is it normal for sealant to crack in a new home?

Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.

Should I wait before resealing?

Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What affects the cost of new build mastic

Jobs vary more than people expect. The main factors:

  • The type of sealant required
  • Any working-time requirements on site
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Asking for a quote

You do not need to know the technical terms. Just tell us:

  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email
  • The type of property
  • Where the property is

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved.

How the visit works

When we get to you, 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 Ascott d'Oyley, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each joint is checked for movement before any work starts.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

Before we arrive

  • Mention any parking rules near the property
  • Keep pets and children clear of the area while we work
  • Tell us about any previous sealing or DIY attempts
