Dewartown Glazing Silicone
Glazing silicone for conservatories, rooflights, glass panels and shower screens for householders, landlords and businesses in Dewartown. Fully insured, ARBOMaster approved and guaranteed for a year.
- Stained, discoloured glazing silicone
- Failed joints on frameless glass
- Water escaping where a screen meets the wall
Why deal with it now?
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Colour agreed with you before we start
- We never seal over old sealant
- More than 20 years in sealant work
- White, clear, grey or coloured to suit, where the product allows

Glazing silicone in Dewartown
Glass replacement isn’t something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. Common call-outs are for a quick top-up bead that didn’t last and leaking glazing joints on a rooflight, on rooflights, conservatory frames and glass-to-frame joints.
In and around a place like Dewartown, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
All our work comes with a 12-month guarantee, wherever you are in Midlothian.

Signs you need glazing silicone in Dewartown
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Most people get in touch after spotting something like this:
- Mouldy sealant around glass panels
- Sealant that was laid over old silicone and failed
- Water escaping where a screen meets the wall
- Failed joints on frameless glass
Historic houses such as Melville Castle, about 4.6 miles west, show how far back building around Dewartown goes.
What your quote should include
- When the joint can take water or movement
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- What guarantee comes with the work
Different surfaces, different methods
Glass balustrade bases
The base of a glass balustrade is normally sealed. Failed sealant there lets water collect.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
What else we do in Dewartown
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
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.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the quote in Dewartown
Jobs vary more than people expect. The main factors:
- Access and height
- How many areas need sealing
- Which sealant suits the joint
- The amount of work
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 the work is at height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- Whether it has been sealed before
- The address or postcode of the job

Glazing silicone in Dewartown: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you let a flat or house near Gorebridge station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Managing a site like Newbattle Community High School? Then its window and door frames need their mastic kept sound, just like a home’s.

Dewartown: your questions answered
Will you come out to Dewartown?
Yes. Dewartown is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Gorebridge station?
Yes, landlords and agents are among the people we work for. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Can you just put new silicone over the old?
New silicone won’t bond to old silicone, so a top-up soon lets water through. We cut out the old sealant first.
What sealant do you use on glazing?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
What guarantee do I get?
All our work has a one-year guarantee, and we are fully insured.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours, depending on how many joints need doing, and we explain the cure time before we leave. Somewhere like Dewartown may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
