New build mastic in Lochgoilhead

About our new build mastic in Lochgoilhead

In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on kitchens, show homes and skirting & floors, and common reasons people get in touch are second-fix sealing on new plots and frame joints opening as the plaster dries.

Around smaller Scottish places like Lochgoilhead, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.

There’s a 12-month guarantee on every job, whatever its size.

Looking after it afterwards

So the new joints stay in good condition:

  • Use the extractor fan every time you shower
  • Photograph failed sealant before it’s redone
  • Do not wait for the house to settle if water is getting through
  • Clean sealant with mild detergent, not abrasives

Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Lochgoilhead questions

Is new build mastic in Lochgoilhead guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Can you do new build mastic in Lochgoilhead?

Yes. Our work covers the whole of Scotland, and Lochgoilhead is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.

How much does new build mastic cost in Lochgoilhead?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

How long will you be here?

A typical job takes 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 I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Do you work for developers?

Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Do you need new build mastic in Lochgoilhead?

New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.

It’s worth asking for a quote if you see:

  • Plot mastic for developers ahead of handover
  • Leaking shower tray seals in a new home
  • Joints pulling apart as timber shrinks
  • Messy sealant that spoils new finishes

For jobs in and around Lochgoilhead, choosing the right material for each joint is as important as a tidy finish.

What your quote should include

  • Whether the sealant suits the joint
  • Are they insured?
  • What the quote includes, VAT included or not
  • What the cure time is

Choosing a sealant specialist

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours in a single home. Around Lochgoilhead, distance and access matter more than parking. Let us know how to find you and how to reach the joints.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. Joints are dried and primed where the product calls for it.
  4. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Tell us if parking is tricky
  • Mention any sign-in or site rules at work premises

What affects the cost of new build mastic

The quote reflects the job in front of us. We take into account:

  • The amount of work
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints
  • Any working-time requirements on site

The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Asking for a quote

What to tell us when you ask for a quote:

  • The rough size of the job
  • A few photos by email, if you can
  • The address or postcode of the job
  • What’s wrong with the joints now

Every job is quoted individually, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details and send pictures if you have them.

Why deal with it now?

If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Why book with us

  • We never seal over old sealant
  • We leave the area clean and tidy
  • Quality sealants from Arbo and Everbuild
  • Anti-fungal sanitary silicone in wet areas

New build mastic around Lochgoilhead

Lochgoilhead is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
