Window mastic in Dumbiedykes, done properly

There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We’re often asked to deal with water coming in at the bottom corners of a door and old mastic that has gone black or come away, across uPVC windows, aluminium frames and timber windows & doors.

Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you are in a tenement flat or a house in Dumbiedykes, the joint between frame and wall is what keeps the weather out.

You get a 12-month guarantee, the same in Dumbiedykes as everywhere else we work.

What affects the quote in Dumbiedykes

The price is agreed before any work begins. It takes into account:

  • Which sealant suits the joint
  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What to tell us for a quote

You do not need to know the technical terms. Just tell us:

  • Pictures of the joints, sent by email
  • Roughly how big the job is
  • How we’d reach the joints
  • Any previous sealing or DIY work

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.

What we do, step by step

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take most of a day for a typical house, less for a few frames. Parking in city streets around Dumbiedykes can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.

  1. We start by checking each window and door with you.
  2. We remove the old mastic and clean the frame and the wall.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. We clear up and check every joint is fully closed.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints
  • Keep pets and children clear of the area while we work

Getting a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Advice

What sealant work can’t fix

It helps to know what we can’t do:

  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Worn gaskets, brush seals or a door that has dropped
  • Damp problems in the wall away from the window

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

Signs you need window mastic in Dumbiedykes

Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.

These are the problems we’re asked about most:

  • Rain getting in at the frame or under the sill
  • Leaking joints at the ends of sills
  • Draughts coming in around windows and doors
  • Cracked or shrunken mastic around the frame

Schools such as Old Royal High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Our hiring checklist

DIY versus a professional finish

If you do try it yourself, take your time over the 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.

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.

What happens if it’s left?

Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Private landlords in Dumbiedykes must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

Why us?

  • Colour agreed with you before we start
  • Anti-fungal sanitary silicone in wet areas
  • A choice of colours where the product allows
  • Over 20 years’ experience

Surface by surface

Composite doors

Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.

Window sills

Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.

Dumbiedykes homes and the weather

Dumbiedykes is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Whitefoord House (about 0.2 miles north) are a reminder that the area around Dumbiedykes has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

For landlords with property near Edinburgh Waverley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Historic houses such as Whitefoord House, about 0.2 miles north, show how far back building around Dumbiedykes goes, and older homes nearby need a sealant that suits their walls.

Dumbiedykes questions

Do you work for landlords with property near Edinburgh Waverley station?

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.

Is window mastic in a coastal place like Dumbiedykes any different?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Can new window sealant be painted?

Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.

Do the sealants smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you seal inside as well as outside?

Yes. Inside, the joint between frame and plaster is sealed neatly.

Is the work guaranteed?

Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Dumbiedykes, along with the rest of our area.
