Facade sealing in Ashford

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

What affects the price in Ashford

Your fixed quote is built from the real scope. It takes account of:

  • Removal of failed or old sealant
  • The size and state of each joint
  • Which sealant the job calls for
  • How accessible the joints are

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • Any dates the work must fit around

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Facade sealing in Ashford, done properly

We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. The enquiries we see most involve air leaks through failed facade joints and sealant pulling away from frames or panels, on window and door perimeters, coping and flashing joints and shopfront frames. A single leaking joint is often how a building in Ashford first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Developers and contractors working in Ashford want mastic that keeps pace with the build: perimeters sealed before scaffold is struck, internal sealant after decoration, snags before handover. Tell us the programme and we’ll quote to it.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Cracked or spalling substrates that need repair before sealing
  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units

If you are not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer.

What we seal

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

FAQs: Ashford

Can you work around term dates at a campus such as Royal Holloway University?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work at a site such as Westgate Industrial Estate, by Ashford?

Yes. Estates, retail parks and business parks around Ashford, Westgate Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

How is access to upper-level joints handled?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we will price the work around it.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Do you cover Ashford?

Yes. We take on work across Ashford, with one number for every area we cover.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Facade sealing in Ashford: the local picture

Ashford is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. A 2-mile radius around Ashford takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

When units on a site such as Westgate Industrial Estate, 1.1 miles north-east of Ashford, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors at a school such as Spelthorne College, sealing has to be finished before term starts.

Ashford is about 6 miles south of Hayes, in Surrey. Commercial clients in Ashford use us for work on facade joints. Our Surrey coverage takes in 379 places, from busy centres to rural villages. We also cover London, around 17 miles from Ashford.

When to call us in Ashford

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

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

  • Previous reseals run over old sealant
  • Old perimeter mastic that has dried out
  • Discoloured or dirty facade joints
  • Water coming in around window frames

When a college such as Brooklands College - Ashford Campus, 0.5 miles to the north-west of Ashford, builds or refurbishes, the mastic package typically has to fit around students and staff.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area
  • What level of public liability insurance do they hold?
  • The named product and why it was chosen

Our process

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If you have more than one building in Ashford, they can often be done on the same visit. Give us your access times and we’ll fit the work in.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Advice

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Confirm the survey covers external sealants in older buildings
  • Plan facade sealing alongside redecoration
  • Keep sills, gutters and drainage paths clear
  • Avoid patch repairs on failed facade joints

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
