Sand mastic near Garthdee

Frames and glazing around Garthdee

Garthdee is within about 3 miles of 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Rented homes near Aberdeen station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Airyhall Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Friendville, about 0.7 miles north, is one of the historic houses in the wider area around Garthdee, and older homes nearby need a sealant that suits their walls.

How we handle sand mastic in Garthdee

Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We’re often asked to deal with silicone on a period window that looks wrong and gaps where the frame meets the masonry, across sash and case windows, timber door frames and stone surrounds.

Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.

A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What affects the quote in Garthdee

There’s no set price list, because no two jobs are the same. The quote depends on:

  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove
  • Working hours on commercial sites
  • The number and length of the joints

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, email us at info@mrmastic.co.uk.

When it isn’t the sealant

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

  • Timber that has rotted
  • Sashes that need overhauling
  • Cracked or broken glass

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

Surfaces we seal

  • Tenement windows
  • Timber door frames
  • Brick reveals
  • Stone surrounds
  • Period & listed homes
  • Sash and case windows

How the job changes by surface

Period and listed homes

Materials matter on listed and conservation-area homes. Like-for-like sand mastic is normally favoured.

Sash and case windows

Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.

How it works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Garthdee, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Tell us if parking is tricky
  • Move anything stored near the joints

Garthdee questions

Is sand mastic in a coastal place like Garthdee any different?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

How is work on the outside of a tenement in Garthdee generally arranged?

Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

How long does sand mastic take?

It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We will tell you when we quote.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Are you fully insured?

Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.

Do you guarantee sand mastic work?

Our one-year guarantee covers every job, sand mastic included.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

Why it’s worth doing now in Garthdee

If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Garthdee, damp can travel a long way before it shows.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Why choose Mr Mastic in Garthdee

  • A 12-month guarantee on all work

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Do not paint over the new mastic
  • Check with your local planning authority if your home is listed
  • Clear gutters so water does not pour onto the windows
  • Sort the mastic before the decorators arrive

Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.

It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
