Facade sealing for Claygate sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Facade sealing in Claygate

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. We work on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints, and what we’re called in for most is cold air coming in at window perimeters and failed seals around shopfront and entrance frames. A single leaking joint is often how a building in Claygate first comes to us: we look at the rest while we are there and tell you what we find.

Around smaller places like Claygate, building work typically 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.

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.

Facade sealing around Claygate: how the place shapes the job

Central London is about 33 miles from Claygate. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

Sites around Claygate get mastic sealed to the drawings and the programme, nothing improvised.

Businesses, contractors and managing agents in Claygate use us for work on facade joints, as part of our coverage of Kent. 931 places across Kent fall within our area, Claygate among them.

Why it’s worth doing now in Claygate

Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. For buildings around smaller places like Claygate, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why choose Mastic Doctor in Claygate

  • Clear, fixed quotes
  • Matching to RAL references, product permitting
  • Colour options checked against the specified product
  • Standard and matched colours in many product ranges

Take a look at our cost guide or our accreditations and insurance.

Looking after the joints

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

  • Never let anyone seal over old sealant
  • Record the product and colour used on each elevation
  • Report water ingress at frames as soon as it shows
  • Check the asbestos register before old mastic is disturbed

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Owners, agents and contractors

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Claygate may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How much existing material needs removing
  • How accessible the joints are
  • Location, for remote and island sites
  • Quantities, in metres or numbers

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • Anything awkward about access or site hours
  • Specification clauses that apply
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email the details over to discuss it first.

What we’re called out for in Claygate

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.

Look out for the following:

  • Draughts around frames and panels
  • Sealant pulling away from frames or panels
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters

For contractors refurbishing units at places like Forstal Business Park (2.9 miles north-west of Claygate), the mastic covers cladding panels, roller-door and window perimeters.

Before you book anyone

  • Their public liability cover
  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long

How to choose a sealant contractor

FAQs: Claygate

Does your area include sites such as Forstal Business Park, near Claygate?

Yes, sites like Forstal Business Park are within our area, along with the rest of Claygate. Send details of the unit and the work through our quote form for a quick quote.

Can the mastic package for our job in Claygate follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
