Sand mastic in Boleside

The process

The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours for a single window, longer for several. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can

Advice

Sand mastic for homes and businesses in Boleside

We work across Boleside renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, stone surrounds and sash and case windows, and the jobs we see most are wind and rain getting in round a sash window and mastic worn away on windows facing the weather.

Mastic can only go onto a dry joint, so outside work in Boleside depends on the weather. Tell us about access to all the windows and doors, upstairs included.

Whatever the size of the job, it’s backed by our 12-month guarantee.

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

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

Boleside homes and the weather

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Peel House (about 4 miles west) nearby, there’s older building stock in the area around Boleside as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Historic houses such as Peel House, about 4 miles west, show how far back building around Boleside goes.

Can I do it myself?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

If you are 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.

Questions from Boleside

Is Boleside within the area you cover?

Yes. Boleside is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

Is Boleside in your area for sand mastic?

Yes, Boleside is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

What do you need from me for a quote?

A short description and the location, plus photos if you have them. We will ask anything else we need to know.

Do I need permission for sand mastic on a listed building?

Check with your local planning authority. They decide whether consent is needed.

When will the new mastic be hard?

The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.

Can new sealant go over the old?

No, because it fails. The old sealant always comes out first.

Is it possible to take out silicone and use sand mastic instead?

Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

Leave it or put it right?

If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a place like Boleside, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • Quality sealants from Arbo and Everbuild
  • We never seal over old sealant
  • 4.9 on Google from 180+ five-star reviews
  • Anti-fungal sanitary silicone in wet areas

How to look after the new joints

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

  • Plan mastic work ahead of painting
  • Ask us before painting near the mastic
  • Avoid heavy scraping on the mastic joint
  • Keep sills and gutters clear so water drains away

Check the mastic when you check the paintwork. Small cracks are easier to deal with early.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
