How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Jobs near Newtown St Boswells are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  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. We walk the finished joints with you before handing over.

Before we start on site

How we handle facade sealing in Newtown St Boswells

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on stone and brick facade joints, perimeter joints where frames meet the structure and cladding panel joints, and what we are called in for most is patch repairs that keep failing and hard, chalky sealant that no longer flexes. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Newtown St Boswells it comes down to the same thing: the right product in a properly prepared joint.

For a site around Newtown St Boswells, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Why deal with it now?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Newtown St Boswells before they leak.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Typical triggers for a call:

  • Air leaks through failed facade joints
  • Failed sealant on precast panel joints
  • Leaks at window and door perimeters
  • Patch repairs that keep failing

Questions to ask before you appoint anyone

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: 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.

Your questions answered

Will you take on work at estates like Tweed Horizons Business Centre, close to Newtown St Boswells?

Yes, sites like Tweed Horizons Business Centre are within our area, along with the rest of Newtown St Boswells. Photos and a short description are enough for a first look.

Is Newtown St Boswells too small for you to travel to?

No. Places such as Newtown St Boswells are covered as much as the big towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you provide access for facade work?

We agree access with the client at the start. Let us know what access is in place or planned.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle
  • Installing or repairing glazing systems

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.

Surfaces we seal

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

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Phasing around occupants
  • Travel to remote or island sites
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • The site address and postcode

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email us.
