Window mastic in Grantown-on-Spey, done properly

Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. Common call-outs are for sealant in the wrong colour for the frame and damp patches on the reveal after heavy rain, on patio & French doors, uPVC windows and aluminium frames.

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 stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Common questions in Grantown-on-Spey

Is there a guarantee on window mastic in Grantown-on-Spey?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Do you cover smaller places like Grantown-on-Spey?

Yes, Grantown-on-Spey is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

Can tenants book the work?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

When is the sealant fully cured?

Different products cure at different speeds, so follow the cure time we give you.

Will new mastic stop draughts?

In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.

Can you quote for more than one area?

Yes. Just list everything you need and we will quote it together.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

How long will my window job take?

The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.

What we do, step by step

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 most of a day for a typical house, less for a few frames. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away, along with any loose debris.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Before we arrive

  • Keep children and pets away from the work area
  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks

Advice

Different surfaces, different methods

Patio & French doors

Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.

Timber windows & doors

Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.

What affects the quote in Grantown-on-Spey

For a quick quote, just ask. What matters most is:

  • The old material and how stubborn it is
  • How easy the joints are to reach
  • The number of rooms or windows
  • Working hours on commercial sites

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • How we’d reach the joints
  • Where the job is, and your postcode
  • If someone has resealed it before
  • The rough size of the job

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

For landlords and businesses

Landlords and letting agents in Grantown-on-Spey can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Paint up to the joint, not over it
  • Wipe condensation off the frames
  • Make sure the drainage slots aren’t blocked
  • Keep paint and stain on wooden frames in good order

Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.

A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
