How long does the job take?

A typical job takes a few hours in a single home. We will confirm how long when we quote.

What colour sealant will you use?

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

Do you work for letting agents?

Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

How long before the joint can be used?

That depends on the sealant used, so follow the cure time we give you when we finish.

New build mastic in Falkirk

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. Typical jobs include skirting joints opening in the first winter and smeared, uneven beads picked up at snagging, across show homes, plot handovers and skirting & floors.

In a town like Falkirk, older streets sit alongside newer estates. New homes need their sealant and floor joints finished properly, and older ones need them renewing.

Your job is guaranteed for a year, as with all our work.

What we cannot put right

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

  • Your warranty claim itself, which is between you and the builder
  • Structural cracks in walls or ceilings
  • Leaks from pipes, valves or wastes, which need a plumber

If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Joints and surfaces we work on

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

Common problems we fix in Falkirk

If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry.

People usually contact us when they notice something like this:

  • Sealant applied over dusty or wet surfaces
  • Leaking shower tray seals in a new home
  • Second-fix sealing on new plots
  • Gaps behind new kitchen upstands

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

What to look for in a quote

  • What insurance they hold
  • What happens if they find a problem under the old sealant
  • Whether all the old sealant comes out first
  • How the surfaces are prepared before sealing

How to choose a mastic man

For landlords and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

How the visit works

You don’t 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. Parking around Falkirk is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  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.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions
  • Where the joints are inside, avoid wetting them before we arrive

Why it’s worth doing now in Falkirk

A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Scottish weather finds any gap, and in a town like Falkirk, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.

Combining jobs into one visit is normally more efficient than separate visits. We will give you a clear price for the lot.

Why book with us

  • Any old sealant cut out fully, not covered over
  • A choice of colours where the product allows
  • ARBOMaster approved applicator
  • Colour agreed with you before any work starts

Take a look at what affects the cost and our reviews.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
