Trusted window mastic in Aberdeen

Leave it or put it right?

Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. For landlords in Aberdeen, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.

How we handle window mastic in Aberdeen

Homes in Aberdeen have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, composite doors and window sills, and the jobs we see most are gaps where the sill meets the wall and water coming in at the bottom corners of a door.

Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.

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

Do you need window mastic in Aberdeen?

Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.

If you can see any of these, it’s time to have the joints looked at:

  • Damp patches on the reveal after heavy rain
  • Black, perished sealant on frames
  • Gaps left after new windows were fitted
  • Leaking joints at the ends of sills

If you live in an older home near Rutherford Church And Church Hall, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Choosing a sealant specialist

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Common questions in Aberdeen

How do repairs to the shared parts of a tenement in Aberdeen get organised?

Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.

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

Yes. We work for landlords and letting agents as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

Will new mastic stop draughts?

In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and we’ll quote it together.

Do you seal inside as well as outside?

Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.

Where is Mr Mastic based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Quotes for window mastic in Aberdeen

Jobs vary more than people expect. The main factors:

  • How much old sealant there is and how hard it is to remove
  • How many areas need sealing
  • Any working-time requirements on site
  • The number and length of the joints

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What we need to know

Before you ask for a quote, have a think about:

  • What’s wrong with the joints now
  • If it’s domestic, commercial or a hotel
  • Roughly how big the job is
  • If someone has resealed it before

We quote each job on its own, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details and send pictures if you have them.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Repaint timber before it’s bare
  • Ventilate rooms so frames do not stay wet inside
  • Avoid blasting the frames with a pressure washer
  • Do not use solvent cleaners on the joint

Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.

A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.

What the job involves on each surface

Patio & French doors

Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

Window sills

Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.

What we do, step by step

The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. Parking in city streets around Aberdeen can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.

  1. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. We tool each bead neatly and check every joint is closed.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Clear items away from the joints we’re working on
  • For business premises, tell us about site rules or sign-in

Advice

Frames and glazing around Aberdeen

Aberdeen is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Aberdeen’s nickname, the Granite City, comes from its stone buildings, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.

If you let a flat or house near Aberdeen station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as Aberdeen Grammar School, the mastic around its windows and doors needs looking after like any other building’s.
