Facade sealing near Frittenden

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Facade sealing in Frittenden, done properly

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. We work on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure, and what we’re called in for most is discoloured or dirty facade joints and leaks at window and door perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Frittenden, preparation and product choice get the time they need.

Around smaller places like Frittenden, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Common questions from Frittenden clients

Will you take on work at estates like Barradale Farm Industrial Estate, close to Frittenden?

Yes. Our area takes in Frittenden and its surroundings, with estates and business parks such as Barradale Farm Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Can you take on a job at a hospital such as Benenden Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Common problems we fix in Frittenden

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Things that typically lead to an enquiry:

  • Cold air coming in at window perimeters
  • Failed sealant on precast panel joints
  • Discoloured or dirty facade joints
  • Sealant pulling away from frames or panels

Projects at schools like Frittenden Church of England Primary School work to term dates, so mastic is programmed tightly.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area
  • Whether primer will be used where the manufacturer specifies it
  • Proof of insurance

Questions to ask before you appoint anyone

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. Acting at the first sign of splitting keeps the fix simple. Around Frittenden, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. If others near Frittenden need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  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

  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Facade sealing in Frittenden: 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 external mastic is timed for workable conditions and agreed with the site manager. Frittenden is about 39 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Units on estates such as Barradale Farm Industrial Estate, 3 miles to the north of Frittenden, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor working at a hospital such as Benenden Hospital, 3.8 miles to the south of Frittenden, perimeter and facade sealing is planned around patients and deliveries.

Frittenden is about 9 miles south of Maidstone, in Kent. Commercial clients in Frittenden can call on us for facade joints. Frittenden is one of 931 places in Kent on our list for facade joints. Brighton is covered too, around 38 miles from Frittenden.

Just outside Frittenden, we also work in Sinkhurst Green (1 mile north), Knox Bridge (1 mile west), Cranbrook Common (2 miles south-west), Sissinghurst (2 miles south-west) and Staplehurst (2 miles north-west). Nearby towns on our patch include Maidstone (9 miles north), Ashford (12 miles east), Sittingbourne (15 miles north-east), Royal Tunbridge Wells (14 miles west), Tonbridge (14 miles west) and Kings Hill (12 miles north-west).

Different surfaces, different methods

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
