Common questions from Town Row clients

Will you take on work at estates like Millbrook Industrial Estate, close to Town Row?

Yes, sites like Millbrook Industrial Estate are within our area, along with the rest of Town Row. A few photographs and the unit address let us price the work.

Is Town Row off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you seal on top of existing 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.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

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. Indoors, the weather is rarely a problem.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

Do you replace failed glazing units?

No. A glazing contractor handles that. What we seal are the joints around frames and panels.

Facade sealing in Town Row

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 damp patches beside frames after rain and previous reseals run over old sealant, on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints. A single leaking joint is often how a building in Town Row 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.

Construction in and around smaller places such as Town Row is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Rural sites near Town Row may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Point out any areas we must not close
  • Let us know about inductions and permits
  • Send any specification or drawings in advance

When to call us in Town Row

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

It’s worth sending us details if you spot any of the following:

  • Cold air coming in at window perimeters
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters
  • Perimeter sealant that has split or peeled away

For contractors at a school such as Rotherfield Primary School, sealing has to be finished before term starts.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • Do they follow the manufacturer’s priming guidance?
  • Their public liability cover
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

Why act early in Town Row

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. One visit to deal with every failing joint makes more sense than several trips to a place like Town Row, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Pricing facade joints depends on quantities, condition and access. Ask us for a fixed quote.

Why us?

  • Workmanship guaranteed for 12 months
  • Work to your specification and the manufacturer’s guidance
  • Fixed quotes based on photographs, drawings or a visit
  • CHAS accredited contractor

Different surfaces, different methods

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported.

Facade sealing in Town Row: the local picture

Town Row sits in one of the drier corners of the country, the South East. 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 34 miles from central London, Town Row is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

With historic properties like Wadhurst Castle, 4.4 miles east of Town Row, in the area, refurbishment work often meets old masonry that needs compatible sealants. New wings at hospitals like Crowborough War Memorial Hospital (to the west of Town Row) bring long runs of window and panel joints to seal.

Town Row is about 3 miles east of Crowborough, in East Sussex. Town Row sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Town Row is one of 308 places we cover in East Sussex for facade joints. Brighton is covered too, around 22 miles from Town Row.

Nearby places we also cover include Rotherfield (1 mile south-west), High Cross (1 mile south), Argos Hill (1 mile south), Mark Cross (1 mile north-east) and Woolbridge (2 miles south) for facade joints. Bigger towns within reach include Hailsham (13 miles south), Crowborough (3 miles west), Uckfield (8 miles south-west), South Malling (15 miles south-west), Heathfield (6 miles south) and Upper Horsebridge (12 miles south).

Quoting for work in Town Row

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • How much existing material needs removing
  • Any access equipment needed
  • Location, for remote and island sites
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • The postcode of the building

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email drawings and photos.
