Facade sealing in Sullington

Facade sealing for commercial buildings in Sullington

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have failed sealant on precast panel joints and water coming in around window frames, we can put it right, on shopfront frames, window and door perimeters and stone and brick facade joints alike. One point of contact handles commercial sealant work in Sullington from the first photographs to the final walk-round, whether it’s one building or several.

For a site near Sullington, 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. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Sullington, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  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

  • Point out any areas we must not close
  • Send your site hours and access windows
  • Flag any permit to work we’ll need

Aftercare for building managers

To get the most from the new sealant:

  • Check the asbestos register before old mastic is disturbed
  • Add perimeter sealant to planned maintenance checks
  • Note when each elevation was last resealed
  • Brief window cleaners about newly sealed joints

Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.

When to call us in Sullington

When the sealant tears down its centre, it has typically been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Common reasons buildings call us in:

  • Weathered joints at frame-to-structure perimeters
  • Sealant pulling away from frames or panels
  • Failed sealant on precast panel joints
  • Weathered facade joints that have lost their grip

When a school such as Thakeham Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

What your quote should include

  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

Surface by surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex.

Facade sealing in Sullington: the local picture

A number of hotels sit less than 2 miles from Sullington. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Sullington is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

Older buildings in the area around Sullington, such as Parham House (2.5 miles west of Sullington), need care when sealed: the product has to suit soft or historic materials. Work at a hotel such as The Old Market Rooms The White Horse Hotel (0.9 miles north-west of Sullington) tends to be programmed around bookings, mastic included.

Your questions answered

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

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.

Is Sullington off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

How long does a typical visit take?

It depends on the scope, though a typical visit 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.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Replacing glass or failed glazing units
  • Providing access systems for the work
  • Render or concrete edges that have broken away

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.
