How we handle facade sealing in Cummertrees

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames, and what we are called in for most is patch repairs that keep failing and cladding panel joints that have opened up. Facilities teams, main contractors and managing agents in Cummertrees tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a site around Cummertrees, we plan the mastic in as few trips as the programme allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Signs you need facade sealing in Cummertrees

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

It’s worth sending us details if you spot any of the following:

  • Failed sealant on precast panel joints
  • Perimeter sealant that has split or peeled away
  • Previous reseals run over old sealant
  • Failed seals around shopfront and entrance frames

For a contractor working at a hospital such as Annan Hospital, 4 miles east of Cummertrees, perimeter and facade sealing is planned around patients and deliveries.

What your quote should include

  • Their public liability cover
  • Their approach to joint depth and backing
  • Who will actually carry out the work
  • What site paperwork they can supply

Questions to ask before you appoint anyone

Your questions answered

Do you take on work at healthcare sites like Annan Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can being near the sea in Cummertrees affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Do you cover Cummertrees?

Yes. Sites across Cummertrees are covered.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can staff carry on working while you are here?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Joints whose design needs changing by the specifier
  • Installing or repairing glazing systems
  • Water getting in through cracked render or porous masonry

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.

What we seal

  • Stone and brick facade joints
  • Window and door perimeters

Facade sealing around Cummertrees: what changes locally

With the shore within about 1 mile, Cummertrees counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Cummertrees is in the east of Scotland, which is drier than the west. Winter mornings can still bring frost and condensation on steel and glass. We programme around it with the site team.

Hotels like The Powfoot Golf Hotel, 0.8 miles to the south-east of Cummertrees, rarely close for long, so refurbishment mastic is phased floor by floor.

Cummertrees is about 12 miles south-east of Dumfries, in Dumfries and Galloway.

Leave it or put it right?

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Cummertrees, a repair visit takes planning, so it’s better to act early.

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

  • Work to your specification and the manufacturer’s guidance
  • CHAS accredited contractor

Take a look at what affects the cost and how we’re accredited.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Where we can, we combine work around Cummertrees with other jobs nearby. Tell us how flexible your dates are.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Make sure the joints can be reached
  • Point out parking and an unloading spot
  • Warn occupants and staff about the work
