About our facade sealing in Guestling

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and sealant pulling away from frames or panels, on shopfront frames, coping and flashing joints and perimeter joints where frames meet the structure. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Guestling it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In the countryside around places like Guestling, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

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

Sites and facades in and around Guestling

The sea is no more than about 2 miles from Guestling. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Central London is about 53 miles from Guestling. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.

Units on estates such as Ivyhouse Industrial Estate, 1.5 miles to the south-west of Guestling, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a healthcare site such as Conquest Hospital, 2.7 miles to the west of Guestling, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Guestling is about 3 miles north-east of Hastings, in East Sussex. Commercial clients in Guestling can call on us for facade joints. Our East Sussex coverage takes in 308 places, from busy centres to rural villages. Sites around Brighton have their own page, about 33 miles away.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Movement beyond what any sealant can handle
  • Work on the window or framing system itself
  • Cracked or spalling substrates that need repair before sealing

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

What we seal

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

What affects the price in Guestling

We price every job individually. The main factors are:

  • The total length or number of joints
  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • The product specified

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Asbestos survey details if the building is older
  • Access details, including height
  • Any dates the work must fit around
  • Specification clauses that apply

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email the details over.

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 with a product suited to glazing perimeters.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Guestling may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We look at the joints, the drawings and the access before pricing.
  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Send asbestos survey details if the building is pre-2000

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Your questions answered

Does your area include sites such as Ivyhouse Industrial Estate, near Guestling?

Yes. We cover Guestling and the area around it, including industrial estates, business parks and retail parks such as Ivyhouse Industrial Estate. Photos and a short description are enough for a first look.

Does a coastal location like Guestling affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Can you work on upper floors?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we’ll plan the work with you.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

When to call us in Guestling

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.

These are often picked up first by site or facilities staff:

  • Draughts around frames and panels
  • Sealant pulling away from frames or panels
  • Water coming in around window frames
  • Hard, chalky sealant that no longer flexes

For contractors at a school such as Guestling Bradshaw Church of England Primary School, sealing has to be finished before term starts.

Comparing quotes

  • Whether primer will be used where the manufacturer specifies it
  • What level of public liability insurance do they hold?
  • The terms of the workmanship guarantee
  • Who will actually carry out the work

Choosing a commercial sealant contractor

When to bring in a specialist

Paperwork matters too. 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.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
