Glazing silicone in Dunnet

Can I do it myself?

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.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

About our glazing silicone in Dunnet

Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we’ll tell you. Common call-outs are for rooflight joints letting water in and shower screens leaking along the wall or tray, across glass-to-glass joints, conservatory frames and glass-to-frame joints.

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.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How it works

The work is kept neat and contained to the area we are working on. Expect the work to take a few hours, depending on how many joints need doing, and we tell you how long to leave it before we go. Around Dunnet, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.

  1. First we agree the joints to be done.
  2. Old sealant is removed from the glass and frame.
  3. The surfaces are cleaned with a suitable solvent.
  4. New glazing silicone goes in and is finished neatly.
  5. We inspect the work and test it where we can.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on
  • Tell us if parking is tricky

Advice

For landlords and businesses

We work for landlords and agents as well as householders. 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.

Why deal with it now?

Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Around Dunnet, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Why us?

  • A choice of colours where the product allows
  • Fully insured
  • Domestic, commercial and hotel work
  • Arbo and Everbuild products

Signs you need glazing silicone in Dunnet

Sunlight breaks sealant down and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.

These are the problems we are asked about most:

  • Water getting into a conservatory at the joints
  • Black or yellowed silicone on glass joints
  • Water escaping where a screen meets the wall
  • A quick top-up bead that didn’t last

In the older streets around Dunnet Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Questions to ask before booking

  • How the colour is chosen
  • Whether VAT is included
  • What preparation is included
  • Whether all the old sealant comes out first

Glass-to-glass joints

These joints are on show, so we take care to leave a neat bead.

Shower screens

Silicone holds the water in on frameless screens. We reseal without scratching the glass.

Windows and doors in Dunnet

Dunnet is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

In and around Dunnet, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Your questions about glazing silicone in Dunnet

Is glazing silicone in a coastal place like Dunnet any different?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Is Dunnet within the area you cover?

Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.

How do I get a quote for glazing silicone in Dunnet?

Size, access and the old material all affect the cost. Call for a quick quote.

Should I try DIY first?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Can landlords and businesses book you?

Yes. We work in homes, commercial premises and hotels.

Which silicone is used for glass joints?

Glass needs a sealant made for glazing. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
