Facade sealing for Fosten Green sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle facade sealing in Fosten Green

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you are dealing with draughts around frames and panels and leaks at window and door perimeters, we can put it right. A specialist sealant contractor works differently from a general builder: in Fosten Green, that means joint design, primers and backing rod as standard.

For a site near Fosten Green, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Fosten Green

Will you take on work at estates like Business Park, close to Fosten Green?

Yes. We cover Fosten Green and the area around it, including industrial estates, business parks and retail parks such as Business Park. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is hospital work, at somewhere like Benenden Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Facade sealing in Fosten Green: the local picture

The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. At about 42 miles from central London, Fosten Green is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

Hospital estates such as Benenden Hospital, 0.9 miles south of Fosten Green, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Fosten Green is about 11 miles west of Ashford, in Kent. Our applicators travel to Fosten Green for work on facade joints. Fosten Green is one of 931 places we cover in Kent. For work in that direction, see our Brighton page, about 38 miles away.

We take on facade joints across the TN27 postcode area. We also cover Clapper Hill (1 mile east), East End (1 mile south), Parkgate (2 miles south-east), London Beach (3 miles east) and Strood (3 miles south-east) for facade joints. Further afield, our area takes in Maidstone (12 miles north), Ashford (11 miles east), Kings Hill (15 miles north-west), Foley Park (13 miles north), Paddock Wood (11 miles north-west) and Tenterden (4 miles south-east).

When to bring in a specialist

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 easy to get wrong without experience.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. One visit to deal with every failing joint makes more sense than several trips to a place like Fosten Green, rather than one at a time. Photos of every joint help us quote for the whole job.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What affects the price in Fosten Green

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Removal of failed or old sealant
  • Working within restricted access windows
  • Which sealant the job calls for
  • Backing rod, priming and other preparation

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them
  • The product your specification calls for
  • Access details, including height

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Clear debris that holds water against joints
  • Share access with other external trades
  • Ask about asbestos in pre-2000 mastic
  • Don’t wait for a second leak before calling

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

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Rural sites near Fosten Green may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open
  • Let us know about inductions and permits

Do you need facade sealing in Fosten Green?

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Typical triggers for a call:

  • Water coming in around window frames
  • Old perimeter mastic that has dried out
  • Draughts around frames and panels
  • Failed sealant on precast panel joints

Recladding or extending a unit at a site like Business Park (1.7 miles south-east of Fosten Green) brings panel joints and frame perimeters into the programme.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Who will actually carry out the work
  • Do they follow the manufacturer’s priming guidance?
  • Is the sealant right for the movement and the substrate?
