Mastic sealing for Gretna Green sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Mastic sealing in Gretna Green, done properly

Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We will confirm the colours available for the specified product. We work on external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms, and the failures we are asked to look at most are patchy repairs in mismatched sealant and occupiers reporting cold air round windows. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Gretna Green it comes down to the same thing: the right product in a properly prepared joint.

For buildings around Gretna Green, we group the work to keep travel and visits down. A list of addresses and photographs lets us quote for them together.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or send photos by email and we will arrange a return visit.

Questions we’re asked in Gretna Green

We manage a building near Gretna Green station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Is a smaller place like Gretna Green outside your area?

Not at all. Gretna Green is within our area. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you check for asbestos in old sealant?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Materials that need asbestos testing before work
  • Failed window or door frames, which need a window contractor
  • Water coming in from the roof or rainwater goods

If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think.

Joints and surfaces we work on

  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • External wall and movement joints
  • Window and door perimeters on blocks
  • Balcony and threshold joints

What the job involves on each surface

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.

Estate-wide resealing programmes

Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.

Block-wide mastic in Gretna Green

Gretna Green is within about 2 miles of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Gretna Green is on Scotland’s drier eastern side. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty.

If you look after a block within reach of Gretna Green station, which lies south-west of Gretna Green, frame and balcony mastic can be renewed on one programme.

Advice

Quoting for work in Gretna Green

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height
  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • When you need the work done
  • The type of building and who uses it
  • The asbestos register, for older buildings
  • The site address and postcode

To get a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.

What happens if it’s left?

Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Around smaller places like Gretna Green, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

What you get with us

  • Our applicators hold CSCS cards
  • Colour agreed before work starts
  • Joints cleaned back to sound surfaces
  • Public liability insurance in place

See what affects the cost and our accreditations.

Do you need mastic sealing in Gretna Green?

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Most enquiries start with one or more of the following:

  • Leaks at window and door perimeters
  • Cracked, hardened mastic round windows on a block
  • Open joints in brickwork or panels
  • Draught complaints from residents or tenants

Trustees of buildings like Old Church and Parish Church can bring frame and external mastic into a planned maintenance list.

What your quote should include

  • How the existing material will be dealt with
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
