Facade sealing for Ashdon sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Ashdon may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we review photos, 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. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Make sure the joints can be reached
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

About our facade sealing in Ashdon

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We plan for that and keep you updated. Site teams most often ask us about failed sealant on precast panel joints and failed seals around shopfront and entrance frames, on shopfront frames, stone and brick facade joints and window and door perimeters. Searching for sealant specialists in Ashdon? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Conversions of older rural buildings near smaller places such as Ashdon bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Ashdon

When the sealant tears down its centre, it has usually 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.

Most enquiries start with one or more of the following:

  • Discoloured or dirty facade joints
  • Air leaks through failed facade joints
  • Old perimeter mastic that has dried out
  • Damp patches beside frames after rain

Extensions at sites like Saffron Walden Community Hospital, 3.3 miles to the south-west of Ashdon, typically sit beside working departments, and the mastic follows strict access rules.

Our contractor checklist

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Work on the window or framing system itself
  • Specialist high-level access methods
  • Joints too narrow for the movement they take, which need redesign

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

Surfaces we seal

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

What happens if it’s left?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Ashdon. Photos of every joint help us quote for the whole job.

Pricing facade joints depends on quantities, condition and access. Ask us for a fixed quote.

Surface by surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Facades, frames and programmes in Ashdon

Central London is about 42 miles from Ashdon. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Ashdon is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

New units and refits on sites such as Ashdon Road Commercial Centre, 2.9 miles to the south-west of Ashdon, need their panel and perimeter joints sealed to the specification. Historic houses such as Audley End House (4.7 miles south-west of Ashdon) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Ashdon is about 4 miles north-east of Saffron Walden, in Essex. We cover commercial sites throughout Ashdon, for single jobs and planned programmes alike. Ashdon is one of 644 places we cover in Essex for facade joints. For work in that direction, see our London page.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Record the product and colour used on each elevation
  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year
  • Check that rainwater leaves the facade the way it was designed to

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

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.

Your questions answered

Is Ashdon too small for you to travel to?

Not at all. Ashdon is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you work on a hospital site such as Saffron Walden Community Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How much does the work cost?

Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or use the quote form.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.
