Facade sealing for businesses in Wouldham

Facade sealing for commercial buildings in Wouldham

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. We work on shopfront frames, stone and brick facade joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are weathered joints at frame-to-structure perimeters and discoloured or dirty facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Wouldham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Wouldham, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Wouldham need work, visits can be combined. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. We walk the finished joints with you before handing over.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Confirm the product named in the specification
  • Tell us which areas need to stay in use

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Your questions answered

Will you plan work around the academic year at somewhere like University for the Creative Arts - Rochester?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Wouldham outside your area?

No. Places such as Wouldham are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Specialist high-level access methods
  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself

If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think before you book.

Surfaces we seal

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

New build and refits around Wouldham

Wouldham is about 26 miles from central London. 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. Wouldham sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

Older buildings in the area around Wouldham, such as Starkey Castle (0.9 miles north of Wouldham), need care when sealed: the product has to suit soft or historic materials. Hospital estates such as St. Catherine's Hospital, 3.1 miles north-east of Wouldham, 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.

Wouldham is about 3 miles west of Chatham, in Kent. We send applicators to Wouldham for facade joints, handled exactly as we handle every other area. Across Kent, 931 places are covered, Wouldham among them. For work in that direction, see our London page (26 miles or so).

We take on facade joints across the ME1 postcode area, for business premises of every kind. Among the streets we cover are High Street, Oldfield Drive and Meadow Way, and sites on any of them can send details for a fixed quote. If your building is just outside Wouldham, we cover Peters Village (1 mile south), Halling (1 mile west), Scarborough (1 mile south-east), Holborough (1 mile south-west) and North Halling (1 mile north-west). A short drive away, we cover Maidstone (6 miles south-east), Sittingbourne (12 miles east), Dartford (12 miles north-west), Sevenoaks (13 miles west), Gravesend (7 miles north-west) and Tonbridge (13 miles south-west).

Around Wouldham

Recent enquiries here include premises near Holborough Marshes, The Thomas Aveling School and The Five Bells pub and the streets around them. The nearest railway station is Halling station, about 0.6 miles west. A little further out are Rochester Castle (3.3 miles north-east) and St. Catherine's Hospital (3.1 miles north-east). For a walk, there’s Blue Bell Hill and Burham Down.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Cost factors for facade joints

Quotes vary with the job. Expect it to depend on:

  • How much there is to seal
  • Which sealant the job calls for
  • How much existing material needs removing
  • Whether the work must be split into stages

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • The type of building and who uses it
  • Any dates the work must fit around

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

When to call us in Wouldham

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Common reasons buildings call us in:

  • Failed sealant on precast panel joints
  • Draughts around frames and panels
  • Weathered facade joints that have lost their grip
  • Leaks at window and door perimeters

University estates such as University for the Creative Arts - Rochester (to the north-east of Wouldham) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

What to look for in a quote

  • What site paperwork they can supply
  • Health and safety accreditation such as CHAS
  • Proof of insurance
  • What the guarantee covers, and for how long
