About our sand mastic in Tayvallich

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on sash and case windows, tenement windows and period & listed homes, and the jobs we see most are a silicone bead on a sash window that spoils the look and tired mastic found when preparing windows for paint.

Mastic can only go onto a dry joint, so outside work in Tayvallich depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.

All of our work is guaranteed for twelve months, in Tayvallich and everywhere else we cover.

Aftercare tips

So the new joints stay in good condition:

  • Ask the planning authority about consent for listed or conservation-area homes
  • Inspect the joints round the windows every year or so
  • Avoid patching sand mastic with silicone
  • Keep sills and gutters clear so water drains away

Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

What affects the quote in Tayvallich

Some jobs are bigger than they look, and some smaller. The main factors:

  • Which sealant suits the joint
  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • Mould in or behind the old joints

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Helping us quote

What to tell us when you ask for a quote:

  • How we’d reach the joints
  • Any previous sealing or DIY work
  • Where the job is, and your postcode
  • The rough size of the job

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Landlords, agents and businesses in Tayvallich

If you manage several properties in or around Tayvallich, several properties can be quoted together. Just tell us the addresses and what each one needs.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

When to call us in Tayvallich

Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.

Keep an eye out for these signs:

  • Gaps where the frame meets the masonry
  • Silicone on a period window that looks wrong
  • Wind and rain getting in round a sash window
  • Old cement repairs round a window that have failed

Around Tayvallich, as everywhere, sand mastic is only as good as the preparation behind it.

Our hiring checklist

How the visit works

Once we’re on site, 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 single window, longer for several. Outside jobs in Tayvallich need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

How to prepare

  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed
  • Mention any tricky access

FAQs for Tayvallich

Can you do sand mastic in Tayvallich?

Yes, Tayvallich is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.

Does the coastal weather in Tayvallich affect outside sealant?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.

Can you replace silicone on a period window with sand mastic?

Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.

Can I choose the sealant colour?

In most cases you can choose. We will tell you which colours the right product comes in and agree one before we start.

Do you work for letting agents?

Yes, often. We can quote for several properties at once.

Do you work for hotels and businesses?

Yes. Hotels, offices and other businesses use us.

Can new sealant go over the old?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Leave it or put it right?

Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Windows and doors in Tayvallich

Tayvallich is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Tayvallich is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.

For an older house near a landmark such as Tayvallich Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
