What new build mastic looks like in Dundee

Dundee is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.

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

Dundee is about 38 miles north of Edinburgh, in Dundee. Homes, rented property, offices and hotels in Dundee can book us for new build mastic, old or new, large or small. The work is guaranteed for a year. 50 places in Dundee are on our list.

New build mastic in Dundee, done properly

Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for kitchen sealant that has pulled off the wall and joints pulling apart as timber shrinks, on bathrooms & en suites, plot handovers and windows & doors.

New flats and houses are still being built in and around Scotland’s cities, and in new homes, sealant and floor joints are often among the first snags.

You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Quotes for new build mastic in Dundee

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

  • The number of rooms or windows
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • The number and length of the joints

The cost reflects the work involved, not guesswork. That is why we ask about the job first.

Photos help, but a description is a good start. Try to tell us:

  • How we’d reach the joints
  • The type of property
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

FAQs for Dundee

Is new build mastic in Dundee guaranteed?

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

Is Dundee in your area for new build mastic?

Yes. Our work covers the whole of Scotland, and Dundee is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.

Do the sealants smell?

Some sealants have a smell while they cure. Ventilation helps.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Is it worth resealing while the house is still settling?

If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.

Are you fully insured?

Yes. We are fully insured.

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Structural cracks in walls or ceilings
  • Movement caused by a poorly fitted tray or bath
  • Deciding who is responsible under a builder’s warranty

If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

Joints and surfaces we work on

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

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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.

Different surfaces, different methods

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.

Skirting and floors

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

Common problems we fix in Dundee

Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.

Common reasons people contact us are:

  • Kitchen sealant that has pulled off the wall
  • New-build shower sealant that has already split
  • Plot mastic for developers ahead of handover
  • Skirting joints opening in the first winter

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

Choosing a sealant specialist

Why deal with it now?

DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. For landlords in Dundee, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.

The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Why us?

  • Sealant colour chosen to suit
  • A choice of colours where the product allows
  • A 12-month guarantee on all work
  • You choose the colour before work begins

How it works

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. Parking in city streets around Dundee can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  3. Joints are vacuumed and cleaned of building dust.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

Before we arrive

  • Move anything stored near the joints
  • Mention any tricky access
  • Let us know about earlier repairs to the joints
