Window mastic in Rosewell, done properly
Homes in Rosewell have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on composite doors, aluminium frames and patio & French doors, and common reasons people get in touch are draughty joints inside around the window and water coming in at the bottom corners of a door.
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.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. In a place like Rosewell, small leaks are easy to put off, 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, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- Anti-fungal sanitary silicone in wet areas
- Neat joints and a tidy finish
- Experience in homes, commercial sites and hotels

Rosewell questions

Yes. We work across all of Scotland, and Rosewell is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.

Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Ventilate rooms so frames do not stay wet inside
- Use gentle cleaners on frames and sealant
- Do not use solvent cleaners on the joint
- Avoid blasting the frames with a pressure washer
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
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.
Frames and glazing around Rosewell
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Historic houses like Melville Castle (about 3 miles north-east) are a reminder that the area around Rosewell has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Lasswade High School Centre are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Rosewell Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we quote for window mastic
Jobs vary more than people expect. What affects the quote:
- The size of the job
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- Any previous sealing or DIY work
- Roughly how big the job is
- The type of property
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, email us at info@mrmastic.co.uk.
What we’re called out for in Rosewell
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Keep an eye out for these signs:
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
If you let a flat or house near Newtongrange station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What to look for in a quote
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- How the colour is chosen
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house from start to finish. Outdoor work around Rosewell depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Mention any tricky access
