Facade sealing for Boughton Corner sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Boughton Corner, done properly

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. We work on perimeter joints where frames meet the structure, cladding panel joints and shopfront frames, and what we are called in for most is discoloured or dirty facade joints and failed sealant on precast panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Boughton Corner it comes down to the same thing: the right product in a properly prepared joint.

Sites around smaller places like Boughton Corner can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When to call us in Boughton Corner

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

If one of these sounds familiar, it’s time for a closer look:

  • Staining on stone next to old sealant
  • Failed seals around shopfront and entrance frames
  • Old perimeter mastic that has dried out
  • Facade joints cracked through the middle

Older buildings in the area around Boughton Corner, such as Godinton House (4.4 miles south-west of Boughton Corner), need care when sealed: the product has to suit soft or historic materials.

How to choose a sealant contractor

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Why deal with it now?

Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer. For buildings around smaller places like Boughton Corner, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

New build and refits around Boughton Corner

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. A number of hotels sit less than 2 miles from Boughton Corner. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Different surfaces, different methods

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in 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. Rural sites near Boughton Corner may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Have the specification and drawings to hand
  • Make sure the joints can be reached
  • Point out any areas we must not close

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Common questions from Boughton Corner clients

Would you work within a site like William Harvey Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can the mastic package for our job in Boughton Corner follow the site programme?

Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

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.

Which sealant do you use on facades?

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 follow the specified product.

Are your applicators CSCS-carded?

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

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
