New build mastic in Sandhurst

New build mastic in Sandhurst

Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have joints pulling apart as timber shrinks and frame joints opening as the plaster dries, we can put it right.

For a small place like Sandhurst, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

You get a one-year guarantee, the same in Sandhurst as everywhere else we work.

How we quote for new build mastic

Every job gets its own quote. These are the things that affect it:

  • The size of the job
  • How easy the joints are to reach
  • Mould in or behind the old joints
  • How many areas need sealing

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What we need to know

To help us quote quickly, let us know:

  • Access, such as stairs, a lift or height
  • What’s wrong with the joints now
  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business

Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details and send photos if you have them.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured.

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.

Do you need new build mastic in Sandhurst?

On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.

The problems people generally mention when they call include:

  • Sealant work across a run of new homes
  • Cracked sealant around new window and door frames
  • Shower seals failing in the first year or two
  • Kitchen sealant that has pulled off the wall

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

What your quote should include

  • How long to leave it before use
  • What the quote includes, VAT included or not
  • Whether they seal over old material or remove it
  • What happens if the job turns out different

DIY sealant or a professional job?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Common questions in Sandhurst

I let a flat near Robertsbridge station. Can you help?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Do you cover Sandhurst for new build mastic?

Do you work for developers?

Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.

Should I go to my builder first?

Report it to the builder first while you are covered. If it is not resolved, we can reseal it properly.

How long before the joint can be used?

Different products cure at different speeds, so follow the cure time we give you when we finish.

Why does sealant fail so quickly in new builds?

A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

How the visit works

At the end, we look at the finished work together. The work normally takes a few hours in a single home, depending on how much there is to do. For a village or hamlet like Sandhurst, 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. 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, with no layer left behind.
  3. Joints are vacuumed and cleaned of building dust.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive

Advice

Why deal with it now?

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 for the lot. Older cottages and farmhouses around Sandhurst can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
