Facade sealing for businesses in St Mary in the Marsh

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Keep pressure washers away from fresh sealant
  • Plan facade sealing alongside redecoration
  • Check the asbestos register before old mastic is disturbed
  • Insist on a full cut-out when joints are renewed

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.

How we handle facade sealing in St Mary in the Marsh

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. If you have previous reseals run over old sealant and draughts around frames and panels, we can help, whatever the surface. One point of contact handles commercial sealant work in St Mary in the Marsh from the first photographs to the final walk-round, whether it’s one building or several.

For a site near St Mary in the Marsh, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in St Mary in the Marsh

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

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

  • Perimeter sealant that has split or peeled away
  • Leaks at window and door perimeters
  • Unsightly perimeter sealant on a visible elevation
  • New sealant peeling off old mastic

When a school such as The Marsh Academy is extended or refurbished, the mastic package is often squeezed into the holidays.

Questions to ask before you book

  • Their public liability cover
  • The terms of the workmanship guarantee
  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Cracked or spalling substrates that need repair before sealing
  • Movement beyond what any sealant can handle
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

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

Joints and surfaces we work on

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

Different surfaces, different methods

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint rather than the system it surrounds.

Your questions answered

Can the mastic package for our job in St Mary in the Marsh follow the site programme?

Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Does a coastal location like St Mary in the Marsh affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, and we build that into the programme.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long does a job like this take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like St Mary in the Marsh are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Confirm the product named in the specification

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
