About our facade sealing in Warninglid

Managing agents and owners in Warninglid ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have air leaks through failed facade joints and leaks at window and door perimeters, we can put it right, on window and door perimeters, shopfront frames and stone and brick facade joints alike. Most enquiries from Warninglid start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Warninglid can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.

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

Surface by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.

Precast concrete panels

Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a day or two for a few elevations, and longer where access has to be moved around the building. If others near Warninglid need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Agree which areas must stay open
  • Let building users know which areas are affected
  • Let us know about inductions and permits

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What we are called out for in Warninglid

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.

Any of the following is a good reason to get the joints checked over:

  • Old perimeter mastic that has dried out
  • Weathered joints at frame-to-structure perimeters
  • New sealant peeling off old mastic
  • Discoloured or dirty facade joints

On a healthcare site such as The Dene Hospital, 3.9 miles south of Warninglid, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

How to choose a sealant contractor

Your questions answered

Does your area include sites such as Crosspot Industrial Estate, near Warninglid?

Yes, sites like Crosspot Industrial Estate are within our area, along with the rest of Warninglid. Photos and a short description are enough for a first look.

Is a hospital such as The Dene Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can you just add new sealant on top?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Is Warninglid in your area?

Yes. We cover Warninglid and the rest of West Sussex, within our coverage of Greater London, South East England and Scotland. For a quote, call the office on 01277 525 020 or email the details over.

Contractors’ notes for Warninglid

At about 34 miles from central London, Warninglid is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Rainfall across the South East, Warninglid included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

Historic houses such as Tyes Place, 1.8 miles to the north-east of Warninglid, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors refurbishing units at places like Crosspot Industrial Estate (2.3 miles south of Warninglid), the mastic covers cladding panels, roller-door and window perimeters.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Add perimeter sealant to planned maintenance checks
  • Investigate damp beside windows promptly
  • Keep sills, gutters and drainage paths clear
  • Insist on a full cut-out when joints are renewed

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

How the quote is worked out

To price the job, we consider:

  • Whether old sealant has to be cut out first
  • How much there is to seal
  • Phasing around occupants
  • How accessible the joints are

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Your programme or deadline
  • The asbestos register, for older buildings
  • Clear photos of the problem areas
  • Where the site is, with the postcode
