Facade sealing in Wallington

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle facade sealing in Wallington

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about draughts around frames and panels and perimeter joints where frames meet the structure, on perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Wallington, preparation and product choice get the time they need.

On a small site around Wallington, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.

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.

How the quote is worked out

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

  • The size and state of each joint
  • The total length or number of joints
  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants

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

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • The product your specification calls for
  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or email the details over.

Building and refurbishing in Wallington

Wallington is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. 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, so we time external mastic for dry faces and agree it with the site team.

School extensions, at buildings such as Wykeham House School, typically run to the summer holidays, mastic included. For contractors refurbishing units at places like Broadcut Retail Park (less than half a mile north-west of Wallington), the mastic covers cladding panels, roller-door and window perimeters.

Questions we’re asked in Wallington

Is Wallington too far out for you?

No. Places such as Wallington are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Broadcut Retail Park, by Wallington?

Yes. Estates, retail parks and business parks around Wallington, Broadcut Retail Park among them, are all within reach. Photos and a short description are enough for a first look.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Different surfaces, different methods

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around Wallington need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Tell staff and tenants when we will be in
  • Make sure the joints can be reached

Ask for a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

What we are called out for in Wallington

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

What tends to prompt an enquiry:

  • Staining on stone next to old sealant
  • Failed sealant on precast panel joints
  • New sealant peeling off old mastic
  • Failed seals around shopfront and entrance frames

For a contractor at a hotel such as Lysses House Hotel, which lies west of Wallington, the mastic often has to be finished before a reopening date.

Questions to ask before you book

  • Proof of insurance
  • The named product and why it was chosen
  • Their approach to joint depth and backing
  • The terms of the workmanship guarantee
