Common problems we fix in Waldershare

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.

Look out for the following:

  • Air leaks through failed facade joints
  • Previous reseals run over old sealant
  • Facade joints cracked through the middle
  • Discoloured or dirty facade joints

Historic houses such as Goodnestone Park, 4 miles to the north of Waldershare, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Our contractor checklist

Facade sealing for commercial buildings in Waldershare

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. Most enquiries involve patch repairs that keep failing and discoloured or dirty facade joints, across stone and brick facade joints, coping and flashing joints and shopfront frames. Whoever orders the work in Waldershare, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In the countryside around places like Waldershare, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

General trades versus 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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Leave it or put it right?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. For buildings around smaller places like Waldershare, 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.

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.

After the work

After handover, a little attention goes a long way:

  • Keep the sealant details on the building file
  • Plan facade sealing alongside redecoration
  • Avoid harsh cleaners on facade sealant
  • Don’t wait for a second leak before calling

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

Surface by surface

Perimeter joints at frames and structure

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

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.

Mastic packages on Waldershare sites

Central London is about 62 miles from Waldershare. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Waldershare is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

For contractors at a school such as Eythorne Elvington Community Primary School, sealing has to be finished before term starts. For contractors refurbishing units at places like Pike Road Industrial Estate, 1.3 miles north-east of Waldershare, the mastic covers cladding panels, roller-door and window perimeters.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Waldershare are normally planned as a single visit, so photographs 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. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000
