How we handle window mastic in Roxburgh

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you are dealing with white mastic on grey or black frames and leaking joints at the ends of sills, we can help, whatever the surface.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

Every job comes with a 12-month guarantee.

Your questions about window mastic in Roxburgh

Is Roxburgh in your area for window mastic?

Yes, Roxburgh is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.

What guarantee comes with window mastic in Roxburgh?

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

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

Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.

Can new window sealant be painted?

Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.

Do you take out the old sealant first?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

How long should I leave it?

It depends on the product. We tell you how long to leave it before we go.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Avoid harsh chemicals near the mastic
  • Paint up to the joint, not over it
  • Use gentle cleaners on frames and sealant
  • Ventilate rooms so frames do not stay wet inside

Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.

Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

What window mastic looks like in Roxburgh

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.

If you live in an older home near Roxburgh Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. In and around Roxburgh, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

What affects the quote in Roxburgh

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

  • Whether the work is at height
  • The size of the job
  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we need to know

To make quoting easier, let us know:

  • The rough size of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • The address or postcode of the job
  • Photos by email, if that is easy

Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand.

What we do, step by step

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. Outdoor work around Roxburgh depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away.
  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.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in

What sealant work can’t fix

New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:

  • A failed sealed unit that has misted up
  • Worn gaskets, brush seals or a door that has dropped
  • Faulty window hardware

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Surfaces we seal

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

For landlords and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Surface by surface

Aluminium frames

Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.

What happens if it’s left?

Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
