Common questions in Lesmahagow

Is glazing silicone in Lesmahagow guaranteed?

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

Is Lesmahagow in your area for glazing silicone?

Yes, Lesmahagow is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available and agree one before we start.

Can you replace a misted double-glazed unit?

No, our work is the silicone. A glazier replaces glass and units.

How long does the job take?

How do I get a quote for glazing silicone in Lesmahagow?

Size, access and the old material all affect the cost. Ask us for a quote.

Can landlords and businesses book you?

Yes, we do. Domestic, commercial and hotel work are all part of what we do.

How we handle glazing silicone in Lesmahagow

Across Lesmahagow, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We are often asked to deal with split or lifting silicone on glass and failed sealant around rooflight glass, across glass-to-glass joints, rooflights and conservatory frames.

Outdoor sealant needs a dry surface, so window work around Lesmahagow is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.

We stand behind the work with a 12-month guarantee.

Different surfaces, different methods

Conservatory frames

Frame joints face sun and rain all year. A fresh bead seals them again.

Glass balustrade bases

The base of a glass balustrade is generally sealed. When it fails, water can sit in the channel.

What happens on the day

At the end, we look at the finished work together. The work normally takes a few hours for most jobs, depending on the size of the job. Around Lesmahagow, 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 look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. We clean and prepare the joint.
  4. We apply and tool the new silicone.
  5. The joints are checked before we leave.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • For indoor joints, keep the area dry beforehand if you can

Advice

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

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

Common problems we fix in Lesmahagow

Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.

The problems people generally mention when they call include:

  • Drips on the inside of a conservatory window
  • Black or yellowed silicone on glass joints
  • Split or lifting silicone on glass
  • Cracked silicone between glass panels

Managing a site like Lesmahagow High School? Then its window and door frames need their mastic kept sound, just like a home’s.

10 questions to ask before booking

Windows and doors in Lesmahagow

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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

Homes close to Lesmahagow Old Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Honest limits

To be straight with you, there are a few things sealant will not fix:

  • A sealed unit that has misted inside
  • Glass that needs replacing
  • Frames that have decayed or split

If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.

What we seal

  • Glass-to-glass joints
  • Conservatory frames
  • Glass-to-frame joints
  • Shower screens
  • Glass balustrade bases
  • Rooflights

Aftercare tips

To keep the joints looking good and working properly:

  • Keep conservatory gutters clear of leaves
  • Ventilate the conservatory to cut condensation
  • Use gentle products around the joints
  • Stick to mild cleaners on glass

Follow the cure time we give you before the joints get wet. From then on, a mild glass cleaner is all it needs.

A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.

Should I try it myself first?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
