Windows and doors in Dairsie

With historic houses such as Hill of Tarvit (about 4 miles south-west) nearby, there’s older building stock in the area around Dairsie as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

Rented homes near Leuchars station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

About our window mastic in Dairsie

The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for draughty joints inside around the window and rushed sealant from a window installation, across aluminium frames, uPVC windows and timber windows & doors.

Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What the job involves on each surface

Patio & French doors

Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.

uPVC windows

uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.

When to call us in Dairsie

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.

Keep an eye out for these signs:

  • Gaps between the frame and the inside reveal
  • Rushed sealant from a window installation
  • Draughts coming in around windows and doors
  • Cracked or shrunken mastic around the frame

Historic houses such as Hill of Tarvit, about 4 miles south-west, show how far back building around Dairsie goes.

Choosing a sealant specialist

What we do, step by step

When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Dairsie may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. First, we go round the frames with you and agree the list.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Where the gap is deep, backing rod goes in first.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. We tool each bead neatly and check every joint is closed.

Before we arrive

  • On commercial sites, let us know about site rules
  • Move anything stored near the joints
  • Mention any parking rules near the property

Advice

Quotes for window mastic in Dairsie

The quote reflects the job in front of us. We take into account:

  • The amount of work
  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • When we can work, for business premises

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Helping us quote

When you contact us, it’s useful to know:

  • The rough size of the job
  • Any previous sealing or DIY work
  • How we’d reach the joints
  • Photos by email, if that’s easy

We quote each job on its own, so the first step is telling us about yours. Simply send an email to info@mrmastic.co.uk and describe the job.

Can I do it myself?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Honest limits

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Rotten timber, which needs a joiner first
  • Draughts through the window seals rather than the frame
  • Penetrating damp from a failed cavity tray or render

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
