Trusted new build mastic in Clachan of Campsie

New build mastic for homes and businesses in Clachan of Campsie

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. Common call-outs are for cracks appearing as a new home settles and new-build shower sealant that has already split, across plot handovers, kitchens and skirting & floors.

New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.

Every job is covered by a one-year guarantee, wherever you are in East Dunbartonshire.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Watch for new gaps as the house dries out
  • Photograph failed sealant before it’s redone
  • Get a leaking seal dealt with right away
  • Raise failed sealant with the developer while you are covered

Follow the cure time we give you before the area gets wet. Most silicones need around a day.

Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely.
  3. We clean out the dust and grit left from the build.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. We tool every joint neatly and tell you when each area can be used.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Let us know about stairs, lifts or work at height
  • Clear items away from the joints we’re working on

Clachan of Campsie: your questions answered

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

Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.

Is Clachan of Campsie within the area you cover?

Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Should I try DIY first?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

When is the best time to reseal in a new build?

It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.

How long should I leave it?

It depends on the product and the conditions. Before we leave, we will tell you the cure time.

Where are you based?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

What does new build mastic cost?

It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.

Do you remove the old sealant?

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

Different surfaces, different methods

Plot handovers

Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.

Bathrooms and en suites

New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

What affects the quote in Clachan of Campsie

The price is agreed before any work begins. It’s based on:

  • Any mould that needs treating
  • How much there is to do
  • Working hours on commercial sites
  • The type of sealant required

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Access, such as stairs, a lift or height
  • If someone has resealed it before
  • The rough size of the job
  • The address or postcode of the job

Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Landlord and commercial work in Clachan of Campsie

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

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.

What happens if it’s left?

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

What you get with us

  • 12-month guarantee on every job
  • Old sealant always removed completely
  • A choice of colours where the product allows
  • ARBOMaster approved applicator

What new build mastic looks like in Clachan of Campsie

Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Clachan of Campsie is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
