Facade sealing for commercial buildings in Baffins

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Baffins. Where sealant is the specified fix, we also take on coping and flashing joints. Site teams most often ask us about leaks at window and door perimeters and cladding panel joints that have opened up, on window and door perimeters, coping and flashing joints and stone and brick facade joints. Searching for sealant specialists in Baffins? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Building work in places the size of Baffins is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Cost factors for facade joints

What shapes the price:

  • The size and state of each joint
  • Distance, for remote addresses
  • The site’s rules and procedures
  • Access and working height

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • What the building is and how it’s used
  • How the joints are reached, and at what height

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or send details through our quote form.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. If neighbouring businesses or buildings around Baffins need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  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
  • Share your working hours and any access restrictions
  • Point out any areas we must not close

Related advice

Should maintenance staff do it?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

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. That’s why many clients bring in a specialist from the beginning.

How the job changes by surface

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 and need a durable external sealant.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Contractors’ notes for Baffins

Baffins sits close to the coast, within about 1 mile. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. A good number of hotels sit less than 2 miles from Baffins. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

When units on a site such as Copnor Bridge Business Centre, less than half a mile west of Baffins, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Building work at universities like University of Portsmouth - Langstone Campus, 1 mile south-east of Baffins, is often timed for the summer, mastic included. Further education sites such as Portsmouth College, 0.5 miles to the east of Baffins, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Why it’s worth doing now in Baffins

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

A quote for facade joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

  • A fixed quote before work starts
  • Over 20 years of commercial sealing

  • Colour options checked against the specified product

Take a look at our cost guide and our accreditations and insurance.

Looking after the joints

After handover, a little attention goes a long way:

  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year
  • Note when each elevation was last resealed
  • Report water ingress at frames as soon as it shows

Keep a note of which product went in and when. Future work can then match the product and colour.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Questions about Baffins

Could you schedule work at a campus like University of Portsmouth - Langstone Campus for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Baffins too small for you to travel to?

Not at all. Baffins is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you call the office on 01277 525 020 or email drawings and photos, describe the access.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.
