New build mastic in Portlethen

New build mastic in Portlethen

Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on plot handovers, windows & doors and skirting & floors, and common reasons people get in touch are gaps behind new kitchen upstands and beads laid onto grit and dust from the build.

Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.

All our work comes with a 12-month guarantee.

When it isn’t the sealant

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Settlement cracks that need a surveyor
  • Your warranty claim itself, which is between you and the builder
  • Movement caused by a poorly fitted tray or bath

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

Surfaces we seal

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

Can I do it myself?

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

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Why it’s worth doing now in Portlethen

Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In an older home around Portlethen, damp from a failed joint can get into timber and plaster.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why book with us

  • We agree the colour with you first
  • Trusted Arbo and Everbuild sealants
  • White, clear, grey or another colour, product permitting
  • Rated 4.9 stars on Google

Landlord and commercial work in Portlethen

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

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Keep water off fresh sealant until it has cured
  • Record problems with dated pictures
  • Don’t seal over failed sealant yourself
  • Wipe joints with warm soapy water

Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

Questions from Portlethen

Will you come out to Portlethen?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

Can you do new build mastic in Portlethen?

Yes. Our work covers the whole of Scotland, and Portlethen is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.

Why does sealant fail so quickly in new builds?

There are usually two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us and we’re fully insured.

Do you take on second-fix sealing for builders?

Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved and we’ll quote.

Are you insured?

Yes, we are fully insured for domestic and commercial work.

Do you guarantee your work?

Yes. All our work carries our one-year guarantee.

Will there be a smell?

There can be a smell while the sealant cures. Opening a window helps.

When to call us in Portlethen

A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.

Signs it’s time to call us include:

  • Worktop and upstand sealant coming away
  • Sealant that never bonded to the surface
  • Sealant work across a run of new homes
  • Untidy sealant flagged on a snagging list

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

Questions to ask before you book
