Signs you need facade sealing in Wrotham

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Common reasons buildings call us in:

  • Previous reseals run over old sealant
  • Discoloured or dirty facade joints
  • Damp patches beside frames after rain
  • Facade joints cracked through the middle

Hotels like The Bull Hotel, under half a mile east of Wrotham, rarely close for long, so refurbishment mastic is phased floor by floor.

Our contractor checklist

How we handle facade sealing in Wrotham

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you have cold air coming in at window perimeters and staining on stone next to old sealant, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Wrotham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Wrotham, 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 usually what’s needed.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Sites and facades in and around Wrotham

Wrotham lies roughly 22 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. A number of hotels sit less than 2 miles from Wrotham. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

Historic houses such as Old Soar Manor (to the south of Wrotham) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When a school such as Wrotham School is extended or refurbished, the mastic package is often squeezed into the holidays.

Wrotham is about 6 miles east of Sevenoaks, in Kent. If you’re looking for facade sealing in Wrotham, we can help. Wrotham is one of 931 places in Kent on our list. Sites around London have their own page, about 22 miles away.

What sets the cost

What shapes the price:

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Site requirements such as inductions and permits
  • Whether the work must be split into stages

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours
  • What the building is and how it’s used
  • Any dates the work must fit around

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or send photos by email.

Questions we’re asked in Wrotham

Does your area include sites such as Invicta Business Park, near Wrotham?

Yes. Our area takes in Wrotham and its surroundings, with estates and business parks such as Invicta Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Sevenoaks Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Wrotham, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  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

  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000

Related advice

Why deal with it now?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. For buildings around smaller places like Wrotham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

A quote for facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • RAL and finish matching where the product range allows
  • Our applicators hold CSCS cards
  • Colours confirmed for the specified product
  • Fully insured

How the job changes 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.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Wrotham can sit alongside others in a wider programme.
