Lochmaddy questions

Do you cover smaller places like Lochmaddy?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.

Does living near the coast affect window mastic in Lochmaddy?

Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.

Do you guarantee window mastic?

Yes, with our one-year guarantee. A yearly look at the joints helps them last.

Can you seal the gap between the frame and the plaster indoors?

Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.

How long does it take to reseal the windows on a house?

Allow anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.

Can you do upstairs windows?

Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.

How long should I leave it?

That depends on the sealant used, so follow the cure time we give you.

Do you work for hotels and businesses?

Yes. We have worked for hotels, offices and other businesses and we are fully insured.

How we handle window mastic in Lochmaddy

The new joint does not 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. Common call-outs are for white mastic on grey or black frames and rushed sealant from a window installation, on aluminium frames, timber windows & doors and uPVC windows.

In and around a place like Lochmaddy, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.

All our work is covered by our 12-month guarantee.

When something else is needed

We’ll always be straight with you, so here’s what sealant cannot fix:

  • Damp coming through the wall itself rather than the frame joint
  • Broken hinges, locks or handles
  • Draughts through the window seals rather than the frame

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Surfaces we seal

  • Timber windows & doors
  • uPVC windows
  • Aluminium frames
  • Composite doors
  • Window sills
  • Patio & French doors

Landlords, agents and businesses in Lochmaddy

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What we are called out for in Lochmaddy

Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.

Signs it’s time to call us include:

  • Gaps where the sill meets the wall
  • Black, perished sealant on frames
  • Draughts coming in around windows and doors
  • Cracked internal joints between frame and plaster

In and around Lochmaddy, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How to choose a mastic man

How the job changes by surface

Timber windows & doors

Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that is a job for a joiner.

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.

Window mastic in Lochmaddy: local notes

Lochmaddy is close to 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 window and door frames, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so the more notice, the better.

For jobs in and around Lochmaddy, choosing the right material for each joint is as important as a tidy finish.

The process

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a few frames, or a day or more for a whole house. Around Lochmaddy, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing.
  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

  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit

Advice

Why act early in Lochmaddy

Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.
