External mastic for homes and businesses in Newhills

Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on façade panels, concrete & block and render & cladding joints, and people most often call us about gaps where render, brick and frames meet and damp patches traced to an open external joint.

External sealant needs dry surfaces, so outdoor work around Newhills is planned around the weather. Tell us how to reach each wall, gutter and roofline.

There’s a 12-month guarantee on every job, large or small.

Outside joints around Newhills

Aberdeen is known as the Granite City, and sealing against granite needs clean, sound edges and a sealant that suits stone. Historic houses like Friendville (about 4.2 miles south-east) are a reminder that the area around Newhills has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

If you let a flat or house near Dyce station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Bucksburn Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Leave it or put it right?

Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Newhills, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Why us?

  • Every job guaranteed for a year
  • We are fully insured
  • Colour agreed with you before we start

Surface by surface

Joints between dissimilar materials

Different materials may need different primers. We prepare both faces so the sealant bonds properly.

Copings and trims

Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.

When it isn’t the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Cracks in the bricks or render themselves, away from the joints
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Movement that is more than a sealant joint can take

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Newhills: your questions answered

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

Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.

Do you cover smaller places like Newhills?

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.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Do you have insurance?

Yes. We are fully insured, with over 20 years’ experience in sealant work.

Where are you based?

We’re based in Crawley, and we work across South East England, London and Scotland.

How do you reach high-level joints?

That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.

What affects the quote in Newhills

Jobs vary more than people expect. The main factors:

  • Whether there’s mould to deal with
  • The number of rooms or windows
  • The type of sealant required
  • Whether old sealant or filler has to be cut out

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Helping us quote

When you call or email, it’s useful to know:

  • How we’d reach the joints
  • Pictures of the joints, sent by email
  • The address or postcode of the job
  • How many joints, rooms or windows are involved

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.

Common problems we fix in Newhills

Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.

The most common problems we see are:

  • Gaps where render, brick and frames meet
  • Moss and dirt in joints with no sealant left
  • Panel joints letting water in
  • Hard, crazed mastic that has stopped moving

If you live in an older home near Old Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What to look for in a quote

  • Whether you can choose the colour
  • How the joint is cleaned and prepared
  • Which sealant they’ll use, and why
  • The length of the guarantee

How to choose a mastic man

How the visit works

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Around Newhills, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. We apply the sealant, tool it and check the whole run.

Before we arrive

  • Let us know about parking restrictions
  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks
