What affects the quote in Falkirk

You’ll get a clear quote before work begins. It takes into account:

  • Which sealant suits the joint
  • Working hours on commercial sites
  • The number and length of the joints
  • Access and height

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • How we’d reach the joints
  • Whether it’s a home or a business
  • Photos by email, if that’s easy
  • Where the job is, and your postcode

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

Window mastic in Falkirk, done properly

Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you are dealing with cracked sealant at the sill ends and cracked internal joints between frame and plaster, we can put it right.

Scottish towns like Falkirk tend to mix older stone-built streets, harled houses and newer estates, and windows range from older sash and case to modern uPVC. The sealant has to suit both the frame and the wall it sits in.

There’s a 12-month guarantee on every job, large or small.

What we do, step by step

On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before we start. Most jobs take most of a day for a typical house, less for a few frames. Parking around Falkirk is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.

  1. First, we go round the frames with you and agree the list.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. Every joint is tooled smooth and checked before we leave.

How to prepare

  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in
  • Move anything stored near the joints

Advice

Different surfaces, different methods

Timber windows & doors

Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.

Window sills

The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Falkirk: your questions answered

Do you work for landlords with property near Falkirk Grahamston station?

Yes. We work for landlords and letting agents as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.

Is Falkirk in your area for window mastic?

Yes, Falkirk 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.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will new mastic stop draughts?

If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Why act early in Falkirk

The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Private landlords in a town like Falkirk must keep homes wind and watertight under the Repairing Standard. Sorting failed joints early is easier than dealing with a tenant’s complaint.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What you get with us

  • You choose the colour before work begins
  • Anti-fungal silicone where joints get wet
  • Quality sealants from Arbo and Everbuild
  • ARBOMaster approved applicator

What we are called out for in Falkirk

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

If you can see any of these, it’s time to have the joints looked at:

  • Hard, cracked sealant around windows
  • Sealant in the wrong colour for the frame
  • Cracked internal joints between frame and plaster
  • Damp patches on the reveal after heavy rain

For an older house near a landmark such as St. Francis Xavier's Roman Catholic Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What your quote should include

  • What the cure time is
  • How long the guarantee is
  • Whether VAT is included
  • Who does the work, and how experienced they are

Frames and glazing around Falkirk

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Letting a property close to Falkirk Grahamston station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Comely Park School, larger buildings have plenty of frames, and the mastic around each one ages.
