About window mastic in Dundee

Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for water coming in at the bottom corners of a door and untidy mastic left by window fitters, across timber windows & doors, aluminium frames and window sills.

You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job.

First, we go round the frames with you and agree the list.
The old mastic is cut out and scraped back to clean surfaces.
Deep gaps get closed-cell backing rod to set the depth.
A flexible exterior sealant is applied in a colour to suit the frame.
We tool each bead neatly and check every joint is closed.

How we quote

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 the work is at height. We take all of that into account in your quote.

For rail, the closest station is Dundee station, about 1.2 miles south of the centre. Nearby you will also find Dudhope Castle (0.7 miles south) and McManus Gallery (0.8 miles south-east). For a walk, there’s Balgay Hill and Trottick Mill Ponds.

Windows and doors across Dundee

Our window mastic work across Dundee covers homes, flats and businesses, from Broughty Ferry, Stobswell and Monifieth to the quieter places in between. Outside sealant needs a dry, clean joint, so the work is planned around the weather.

Our work covers the whole of Scotland, Dundee included. Longer journeys are planned in advance, and outdoor work around the weather. Along the coast in Dundee, window and wall joints facing the sea take the brunt of the weather, so they’re often the first to fail. Good preparation and the right sealant help it cope.

Dundee: For landlords with property near Dundee station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Scottish School of Contemporary Dance are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints

To keep the joints looking good and working properly:

Look round the frames every year or so
Use gentle cleaners on frames and sealant
Keep drainage slots and sill grooves clear
Don’t use solvent cleaners on the joint

A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just send an email to info@mrmastic.co.uk.

Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

For landlords and businesses

We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Leave it or put it right?

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway.

Different surfaces, different methods

Aluminium frames

Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.

Patio & French doors

Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

Dundee: your questions answered

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.

Do you seal inside as well as outside?

Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

How long does it take to reseal the windows on a house?

Allow a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.

What should I tell you?

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

Will new mastic stop draughts?

Yes, where the draught is at the frame edge. We check where the draught is before we start.

Can landlords and businesses book you?

Yes. As well as householders, we work for landlords, agents, businesses and hotels.
