How we handle window mastic in Birkhill

Homes in Birkhill 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. We work on composite doors, uPVC windows and window sills, and common reasons people get in touch are gaps between the frame and the inside reveal and mastic that has split away from the wall.

Mastic can only go onto a dry joint, so outside work in Birkhill depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.

A one-year guarantee comes as standard, so you’re covered after we have gone.

Birkhill homes and the weather

Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Historic houses like Camperdown House (about 1 mile south-east) are a reminder that the area around Birkhill 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.

Rented homes near Invergowrie station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Lawside Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Birkhill is about 3 miles north-west of Dundee, in Dundee. Jobs in Birkhill get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Birkhill is one of 50 places in Dundee we cover.

How it works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Outside jobs in Birkhill need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

  1. We check each frame and agree which ones need doing.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Deep gaps are filled with backing rod to set the depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Finally we tidy up and check each joint.

How to prepare

  • Mention if the joints have been sealed before
  • Clear the area around the work
  • Let us know about stairs, lifts or work at height

Why act early in Birkhill

Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Do you need window mastic in Birkhill?

Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.

The problems people generally mention when they call are:

  • Mastic that is falling out in pieces
  • Rushed sealant from a window installation
  • Rain getting in at the frame or under the sill
  • White mastic on grey or black frames

Camperdown House, about 1 mile south-east, is one of the historic houses in the wider area around Birkhill, and older homes nearby need a sealant that suits their walls.

Choosing a sealant specialist

When something else is needed

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Broken hinges, locks or handles
  • 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 send an email to info@mrmastic.co.uk and we will tell you honestly.

What we seal

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

How the job changes by surface

Aluminium frames

Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.

uPVC windows

Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

Birkhill: your questions answered

Is Birkhill within the area you cover?

Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Invergowrie station?

Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

Can you seal the gap between the frame and the plaster indoors?

Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.

Can I paint over the new sealant?

Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Do you have insurance?

Yes. We are fully insured.

Do you have sealant for grey or black windows?

Yes. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

Landlord and commercial work in Birkhill

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
