New build mastic in Devonside

New build mastic for homes and businesses in Devonside

Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. We work on plot handovers, bathrooms & en suites and skirting & floors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and leaking shower tray seals in a new home.

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

Whatever the size of the job, it’s backed by our one-year guarantee.

When to call us in Devonside

Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.

Keep an eye out for these signs:

  • Gaps behind new kitchen upstands
  • Joints pulling apart as timber shrinks
  • Sealant that never bonded to the surface
  • Shower seals failing in the first year or two

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

Questions from Devonside

Can you help a landlord with a rental near Alloa station?

Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.

Do you cover Devonside for new build mastic?

Yes, Devonside is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.

Should I wait before resealing?

That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.

Can you work from my snagging list?

Yes. Send the list and a few photos of the sealant items. We will tell you if anything on it isn’t a sealant job.

How long does the job take?

A typical job takes anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us.

What information do you need?

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

Do you take on second-fix sealing for builders?

Yes. We work through plots to your schedule. Tell us the plots and the joints involved for a clear quote.

How the visit works

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Devonside may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. First we work through your snagging list or plot schedule with you.
  2. Failed or untidy sealant is cut out completely.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. Each area is checked and left with its cure time.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access
  • Let us know about earlier repairs to the joints

When it isn’t the sealant

To be straight with you, some problems need a different trade:

  • Cracked trays, tiles or worktops
  • Deciding who is responsible under a builder’s warranty
  • Movement caused by a poorly fitted tray or bath

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Where we work in Devonside

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

Leave it or put it right?

The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In an older home around Devonside, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

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

Why us?

  • Sealant colour chosen to suit
  • We never seal over old sealant
  • Anti-fungal silicone where joints get wet
  • We’re fully insured

What the job involves on each surface

Kitchens

New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.

Windows and doors

On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.

What affects the cost of new build mastic

Some jobs are bigger than they look, and some smaller. The main factors:

  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • How easy the joints are to reach
  • The type of sealant required

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • The problem you’ve noticed
  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel
  • Photos by email, if that is easy

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
