Window mastic for Portree homes and businesses

What the job involves on each surface

Composite doors

Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.

uPVC windows

Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.

How we handle window mastic in Portree

The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on window sills, composite doors and aluminium frames, and the jobs we see most are gaps between the frame and the inside reveal and cracked or shrunken mastic around the frame.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.

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

Do you need window mastic in Portree?

Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.

Any of these means the joints need attention:

  • Draughts coming in around windows and doors
  • Gaps left after new windows were fitted
  • White mastic on grey or black frames
  • Damp patches on the reveal after heavy rain

For site and facilities teams at buildings such as Portree High School, its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints

To keep the joints looking good and working properly:

  • Keep solvents and bleach off the sealant
  • Walk round the house once a year and look at the joints
  • Keep timber frames painted
  • Don’t paint over the silicone

Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.

Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Questions from Portree

Is Portree within the area you cover?

Yes, Portree is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is window mastic in a coastal place like Portree any different?

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.

Are you fully insured?

Yes, we are fully insured for every job we do.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Can I paint over the new sealant?

It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before any work starts.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

What we do, step by step

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a morning for a couple of windows and a door. Outside jobs in Portree need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. We check each frame and agree which ones need doing.
  2. We remove the old mastic and clean the frame and the wall.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Finally we tidy up and check each joint.

Preparing for the visit

  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive

Why act early in Portree

Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. In an older home around Portree, damp from a failed joint can get into timber and plaster.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Why us?

  • Domestic, commercial and hotel work
  • We’re fully insured
  • We agree the colour with you first
  • Approved under the ARBOMaster scheme

Windows and doors in Portree

Portree 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. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Homes close to St Columba's Episcopal Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Portree (Gaelic: Port Rìgh) is in Highland. Homes, rented property, offices and hotels in Portree can book us for window mastic, old or new, large or small. Every job comes with our 12-month guarantee. Across Highland, we cover 253 places, and Portree is one of them.

Postcode districts we cover here for window mastic: IV51. You will find streets such as Somerled Square, Viewfield Square and Ionad Mharsco.
