Aftercare tips

Looking after new joints is easy:

  • Clear any debris from frame drain holes
  • Keep paint and stain on wooden frames in good order
  • Avoid harsh chemicals near the mastic
  • Keep paint off silicone joints

Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.

Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

Window mastic for homes and businesses in Carbost

Homes in Carbost have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with cracked internal joints between frame and plaster and sealant in the wrong colour for the frame, we can put it right, on patio & French doors, uPVC windows and window sills alike.

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

There’s a 12-month guarantee on every job, whatever its size.

Signs you need window mastic in Carbost

Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.

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

  • Hard, cracked sealant around windows
  • Old mastic that has gone black or come away
  • Rain getting in at the frame or under the sill
  • Whistling draughts around closed windows

For jobs in and around Carbost, choosing the right material for each joint is as important as a tidy finish.

What to look for in a quote

  • Is VAT in the price?
  • When the joint can take water or movement
  • How the surfaces are prepared before sealing
  • Which colour the sealant will be

Choosing a sealant specialist

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes a few hours for a few frames, or a day or more for a whole house. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • On commercial sites, let us know about site rules
  • Clear the area around the work

Work for landlords, hotels and businesses

If you manage several properties in or around Carbost, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.

Landlords and letting agents in Carbost can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Can I do it myself?

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 fails, we can still redo it.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

When it is not the sealant

It helps to know what we cannot do too:

  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Faulty window hardware
  • Damp coming through the wall itself rather than the frame joint

If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.

What we seal

  • Aluminium frames
  • Window sills
  • Timber windows & doors
  • Patio & French doors
  • Composite doors
  • uPVC windows

How we quote for window mastic

We do not publish a price list. The quote depends on:

  • Whether old sealant or filler has to be cut out
  • How much there is to do
  • Mould in or behind the old joints
  • Working hours on commercial sites

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
  • Roughly how big the job is
  • Any previous sealing or DIY work

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

Window mastic in Carbost: local notes

Carbost is within about 1 mile 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 window and door frames, 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.

In and around Carbost, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Your questions about window mastic in Carbost

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

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Will you come out to Carbost?

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

Will new mastic stop draughts?

Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.

Can you do upstairs windows?

Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.

How long before the joint can be used?

That depends on the sealant used, so please follow the time we give you.

What do you need from me for a quote?

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

Is the new sealant paintable?

Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.
