Facade sealing in Shawhead, done properly

Every facade quote starts with how the joints will be reached.

Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Shawhead: questions and answers

What site paperwork comes with a job in Shawhead?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will you fit the mastic around our build programme in Shawhead?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.

Do you replace windows or glass?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

How many days will you need on site?

It depends on the scope, but the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we will set out a timescale with the quote.

Maintenance after handover

Once the work is signed off, these steps help:

  • Check that rainwater leaves the facade the way it was designed to
  • Never let anyone seal over old sealant
  • Walk the elevations once or twice a year
  • Share access with other external trades

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Shawhead can form part of a wider programme.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: for instance 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.

Why deal with it now?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. For buildings near Shawhead, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

When something else is needed

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

  • Cracked or spalling substrates that need repair before sealing
  • Movement beyond what any sealant can handle
  • Replacing glass or failed glazing units

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

What we seal

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

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Travel to smaller Scottish places like Shawhead is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
