New build mastic in Stronmilchan

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you’re dealing with sealant that never bonded to the surface and cracks appearing as a new home settles, we can help.

Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.

Each job carries a 12-month guarantee, large or small.

How to look after the new joints

After the cure time, these simple habits help:

  • Do not seal over failed sealant yourself
  • Look at the sealant regularly in the first couple of years
  • Keep pictures and emails about snagging items
  • Wait for the cure time before using a resealed shower

Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.

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.

Different surfaces, different methods

Show homes

Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.

Kitchens

Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

New build mastic in Stronmilchan: local notes

The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.

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

Why act early in Stronmilchan

The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In a place like Stronmilchan, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

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 we need extra access for height. We take all of that into account in your quote.

What we do, step by step

You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours in a single home for a typical job. Outside jobs in Stronmilchan need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  3. Joints are dried and primed where the product calls for it.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. We check every joint and leave you with the cure times.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions

DIY versus a professional finish

If you are 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 does not work out, we can still put it right.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

When to call us in Stronmilchan

The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.

  • Second-fix sealing on new plots
