Trusted new build mastic in Grimness

New build mastic in Grimness, done properly

We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. Typical jobs include gaps behind new kitchen upstands and sealant work across a run of new homes, on plot handovers, kitchens and windows & doors.

Work in a place like Grimness is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.

Every job comes with a one-year guarantee, wherever you are in the Orkney Islands.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Do you work for hotels and businesses?

How long should I leave it?

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

Can you work from my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.

When to call us in Grimness

Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.

People generally contact us after spotting something like this:

  • Gaps between new skirting and floors
  • Joints pulling apart as timber shrinks
  • Sealant work across a run of new homes
  • Sealant applied over dusty or wet surfaces

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

How to choose a mastic man

When something else is needed

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Structural cracks in walls or ceilings
  • Cracked trays, tiles or worktops
  • A tray or bath that is not properly supported, until it’s fixed

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

Surfaces we seal

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

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

How to look after the new joints

To keep the joints looking good and working properly:

  • Avoid running a DIY bead over the old one
  • Don’t wait for the house to settle if water is getting through
  • Put sealant faults on your snagging list early
  • Open a window or run the fan after bathing

Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

New build mastic around Grimness

Grimness is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.

Why deal with it now?

Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a place like Grimness, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How the visit works

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. Outside jobs in Grimness need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely down to clean surfaces.
  3. Joints are vacuumed and cleaned of building dust.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit

How to get a quote
