Facade sealing near Lilyvale

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

How we handle facade sealing in Lilyvale

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on cladding panel joints, coping and flashing joints and shopfront frames, and the usual reasons a site gets in touch are gaps between rainscreen or cladding panels and new sealant peeling off old mastic. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lilyvale is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Lilyvale, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Work on the window or framing system itself
  • Movement beyond what any sealant can handle
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Lilyvale are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  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 is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or use the quote form with what you know.

Advice

Facade sealing around Lilyvale: what changes locally

Rainfall across the South East, Lilyvale included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Central London is about 53 miles from Lilyvale. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

For contractors at a school such as Smeeth Community Primary School, sealing has to be finished before term starts. Historic houses such as Westenhanger Castle, 2.7 miles south-east of Lilyvale, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Lilyvale is about 5 miles east of Ashford, in Kent. Businesses, contractors and managing agents in Lilyvale use us for work on facade joints. Across Kent, 931 places are covered, Lilyvale among them. We also cover Brighton, around 52 miles from Lilyvale.

Questions we’re asked in Lilyvale

Is a smaller place like Lilyvale outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is Evegate Business Park, near Lilyvale, within your area?

Yes, sites like Evegate Business Park are within our area, along with the rest of Lilyvale. Photos and a short description are enough for a first look.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

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

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Do you replace windows or glass?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Brief window cleaners about newly sealed joints
  • Combine resealing with other works that need access
  • Record the product and colour used on each elevation
  • Avoid patch repairs on failed facade joints

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.

When to call us in Lilyvale

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

Typical triggers for a call:

  • Draughts around frames and panels
  • Discoloured or dirty facade joints
  • Old perimeter mastic that has dried out
  • Facade joints cracked through the middle

Hospital estates such as William Harvey Hospital (to the north-west of Lilyvale) 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.

Before you book anyone

  • Who will actually carry out the work
  • How the joint faces will be prepared and primed
  • How they’ll work around occupants
  • How long is the guarantee, and what does it include?

Questions to ask before you appoint anyone

What the job involves on each surface

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.
