New build mastic in Preston

New build mastic in Preston

We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant usually lacks. If you are dealing with frame joints opening as the plaster dries and sealant that never bonded to the surface, we can help, whatever the surface.

For a place like Preston, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Common questions in Preston

Can you do new build mastic in Preston?

Yes, Preston is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

Is Preston within the area you cover?

Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.

My new home is still under warranty. Should I contact you?

Start with the builder if you are in the snagging or warranty period. Once that is done, or if they will not put it right, we can reseal it properly.

Where do you work from?

We are based in Crawley, and we work across South East England, London and Scotland.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done.

Do you use white or clear sealant?

It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Are you ARBOMaster approved?

Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Surface by surface

Skirting and floors

Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.

Show homes

Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.

New build mastic around Preston

Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

Whether the job is in Preston itself or nearby, the right material for each joint matters as much as a neat finish.

What affects the cost of new build mastic

Call for a quick quote. What matters most is:

  • Any mould that needs treating
  • The amount of work
  • How easy the joints are to reach
  • The type of sealant required

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What we need to know

To help us quote quickly, please include:

  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • How many joints, rooms or windows are involved
  • How we’d reach the joints

There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What happens on the day

On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. The work normally takes anything from a few hours to several days, depending on the number of plots. For a place like Preston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. First we work through your snagging list or plot schedule with you.
  2. The old bead comes out in full, with no layer left behind.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. We check every joint and tell you how long each needs to cure.

How to prepare

  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Follow the cure time we give you
  • Open a window or run the fan after bathing
  • Put sealant faults on your snagging list early
  • Avoid running a DIY bead over the old one

Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.

Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

What we can’t put right

In fairness, there are a few things sealant will not fix:

  • Movement caused by a poorly fitted tray or bath
  • Plumbing faults behind the sealant
  • Broken tiles or a split tray

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

What we are called out for in Preston

The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.

Signs it’s time to call us include:

  • Sealant that never bonded to the surface
  • Worktop and upstand sealant coming away
  • Sealant work across a run of new homes
  • Messy sealant that spoils new finishes

Around Preston, as everywhere, new build mastic is only as good as the preparation behind it.
