What affects the quote in Bishopbriggs

We quote each job individually. These are the things that affect it:

  • How easy the joints are to reach
  • When we can work, for business premises
  • How much old sealant there is and how hard it is to remove
  • The size of the job

Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Helping us quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Access, such as stairs, a lift or height
  • The rough size of the job
  • Whether it has been sealed before
  • What’s wrong with the joints now

Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Sand mastic in Bishopbriggs

If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, we can put it right, whatever the surface.

In a town like Bishopbriggs, stone-built older streets usually sit alongside harled houses and newer estates, so windows range from sash and case in older buildings to uPVC on newer homes. The sealant has to suit both the frame and the wall it sits in.

You are covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Common problems we fix in Bishopbriggs

Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.

People normally contact us after spotting one of these:

  • Open joints round the window box
  • A silicone bead on a sash window that spoils the look
  • Mastic round period door frames that has failed
  • Cement or filler used on old window joints that has cracked

If you live in an older home near Colston Wellpark Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions to ask before you book

  • What happens if they find a problem under the old sealant
  • How the joint is cleaned and prepared
  • Is VAT in the price?
  • Whether all the old sealant comes out first

How to choose a mastic man

Can I do it myself?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’re 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 fails, we can still redo it.

Why it’s worth doing now in Bishopbriggs

A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Private landlords in a town like Bishopbriggs must keep homes wind and watertight under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

How it works

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It normally takes anything from a few hours to a full day, depending on how many windows. Parking around Bishopbriggs is rarely difficult, though older streets in the centre can be tight. If you’re in a flat with a shared stair or a door entry system, let us know when you book.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • Move anything stored near the joints
  • Mention any sign-in or site rules at work premises
  • Try not to wet indoor joints just before the visit

Bishopbriggs homes and the weather

Historic houses like Provand's Lordship (about 3.2 miles south) are a reminder that the area around Bishopbriggs has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.

Managing a site like Bishopbriggs Academy? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Bishopbriggs station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
