Facade sealing for Allanton sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Facade sealing in Allanton, done properly

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on cladding panel joints, coping and flashing joints and window and door perimeters, and the failures we’re asked to look at most are staining on stone next to old sealant and failed sealant on precast panel joints. Facilities teams, main contractors and managing agents in Allanton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In smaller places such as Allanton, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What affects the price in Allanton

A fixed quote reflects the actual work. It takes account of:

  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Travel to remote or island sites
  • Removal of failed or old sealant

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • The postcode of the building
  • Any dates the work must fit around
  • The product your specification calls for
  • Photos of the joints, close up and from further back

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Questions about Allanton

Is a hospital such as University Hospital Wishaw somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Do you cover business parks and estates near Allanton, such as Barncluith Business Centre?

Yes. Our area takes in Allanton and its surroundings, with estates and business parks such as Barncluith Business Centre included. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months on every job.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What we can’t put right

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

  • Water getting in through cracked render or porous masonry
  • Joints too narrow for the movement they take, which need redesign
  • Specialist high-level access methods

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we seal

  • Shopfront frames
  • Cladding panel joints
  • Window and door perimeters
  • Coping and flashing joints
  • Stone and brick facade joints
  • Perimeter joints where frames meet the structure

What happens if it’s left?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Renewing every failing joint on one visit is the sensible approach for a place like Allanton. Send photographs and we’ll quote for everything together.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Colour options checked against the specified product
  • 12-month guarantee on workmanship
  • Coloured sealants to suit the setting, where available
  • Sealing commercial buildings since 2005

After the work

After handover, these steps help:

  • Don’t wait for a second leak before calling
  • Insist on a full cut-out when joints are renewed
  • Note when each elevation was last resealed
  • Plan facade sealing alongside redecoration

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Where we can, we combine work around Allanton with other jobs nearby. Let us know if your dates have any give.

  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. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  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.

What we need from you

  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
