Gutter sealing in Glasgow, done properly

Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter itself has failed, we say so. We work on garage door frames, soffit joints and roofline trims, and the jobs we see most are gaps along fascia and soffit joints and water dripping where gutter sections meet.

In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Glasgow, repairs to shared parts are normally agreed between the owners, often through a property factor.

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

How we quote for gutter sealing

For a quick quote, just ask. The main things that affect it are:

  • The number of rooms or windows
  • Any mould that needs treating
  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • Roughly how big the job is
  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs

Need a quote? Please email us at info@mrmastic.co.uk and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.

When it isn’t the sealant

It helps to know what we can’t do too:

  • Fascias that need replacing
  • Cracked, split or warped gutter sections
  • Leaks from the roof rather than a joint

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

  • Roofline trims

FAQs for Glasgow

Who arranges sealant work on the shared parts of a tenement in Glasgow?

Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.

Do you cover Glasgow for gutter sealing?

Yes. We work across all of Scotland, and Glasgow is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.

Can you reach high gutters?

That depends on the building. Tell us the height and what’s around the gutter and we will confirm what’s needed.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

What guarantee comes with the job?

All our work carries a 12-month guarantee, and we are fully insured.

Do you work for landlords and businesses?

Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status.

Will you leave a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Aftercare tips

To keep the joints looking good and working properly:

  • Check that water runs out of the downpipes
  • Get a dropping gutter looked at quickly
  • Do not lean ladders against the gutter itself
  • Clear leaves and moss from the gutters

A sagging gutter needs its brackets checked. Movement will pull the joints open again.

Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.

Garage door frames

Resealing a garage door frame keeps rain and draughts out.

Soffit joints

We choose a sealant colour that suits the soffit.

Gutter sealing in Glasgow: local notes

Historic houses like Tenement House (about 1 mile north) are a reminder that the area around Glasgow has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

Historic houses such as Tenement House, about 1 mile north, show how far back building around Glasgow goes. Schools such as Our Lady and St Margaret's Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

The process

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a few hours. Parking in city streets around Glasgow can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.

  1. First we agree which joints need sealing.
  2. We clean out each joint.
  3. We make sure everything is dry.
  4. We apply exterior or gutter sealant and finish it neatly.
  5. The joints are checked once sealed.

How to prepare

  • Clear the area around the work
  • Mention if the joints have been sealed before
  • Try not to wet indoor joints just before the visit

Advice

Common problems we fix in Glasgow

Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up, which is why we look before we seal.

People usually contact us after spotting something like this:

  • Damp on an inside wall under a dripping gutter
  • Old gutter sealant that has let go
  • Garage door frames letting rain in
  • Open joints in fascias and soffits

Rented homes near Anderston station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.
