Sand mastic in Gilmerton

Sand mastic in Gilmerton, done properly

Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you’re dealing with mastic dropping out of the joint and weathered mastic on the most exposed windows, we can put it right.

In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Gilmerton, and in a tenement the outside of the building may be a shared repair.

All of our work is guaranteed for twelve months.

Sand mastic in Gilmerton: local notes

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.

If you let a flat or house near Shawfair station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Gracemount High School, the mastic around its windows and doors needs looking after like any other building’s.

What affects the quote in Gilmerton

We don’t publish a price list. What we look at:

  • The number and length of the joints
  • How much old sealant there is and how hard it is to remove
  • The product the joint needs
  • How many rooms, windows or areas are involved

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Helping us quote

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

  • What’s wrong with the joints now
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved

To get a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. You will have a clear quote before any work starts.

How it works

We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Gilmerton, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about access, such as stairs, a lift or high-level joints
  • On commercial sites, let us know about site rules

Different surfaces, different methods

Period and listed homes

Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

When it is not the sealant

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

  • Whether work needs listed building consent
  • Broken panes
  • Timber that has rotted

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

Surfaces we seal

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

Do you need sand mastic in Gilmerton?

Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.

It’s worth asking for a quote if you see:

  • A silicone bead on a sash window that spoils the look
  • Wind and rain getting in round a sash window
  • Window mastic to renew ahead of painting
  • Mastic round period door frames that has failed

Historic houses such as Melville Castle, about 1.4 miles south-east, show how far back building around Gilmerton goes, and older homes nearby need a sealant that suits their walls.

Questions to ask before you book

  • Are they insured?
  • What happens if they find a problem under the old sealant
  • What preparation is included
  • When the joint can take water or movement

Yes, Gilmerton is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.

Do you work for landlords with property near Shawfair station?

Yes. We work for landlords and agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access.

Should I check with the council before work on a listed or conservation-area home?

Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.

Do you offer different sealant colours?

Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.

Can new sealant go over the old?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

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’ll give you a better idea when we quote.

Do you work for hotels and businesses?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

Why it’s worth doing now in Gilmerton

New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Wind-driven rain gets into any failed joint on the outside of a city building, and in Gilmerton, damp can spread through stone and plaster before anyone sees it.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
