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

Facade sealing in Wendens Ambo, done properly

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on commercial buildings in Wendens Ambo. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with weathered joints at frame-to-structure perimeters and cladding panel joints that have opened up, we can help, whatever the surface. Searching for sealant specialists in Wendens Ambo? We’ve been sealing commercial buildings since 2005.

Construction in and around smaller places such as Wendens Ambo is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Render or concrete edges that have broken away
  • Work on the window or framing system itself
  • Specialist high-level access methods

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we seal

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

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. If others near Wendens Ambo need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We plan access and the order of elevations with the client.
  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. We hand over with our 12-month workmanship guarantee.

What we need from you

Related advice

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Check the asbestos register before old mastic is disturbed
  • Avoid harsh cleaners on facade sealant
  • Clear debris that holds water against joints
  • Avoid patch repairs on failed facade joints

Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. One visit to deal with every failing joint makes more sense than several trips to a place like Wendens Ambo, rather than one at a time. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why us?

  • Colours chosen to suit frames, cladding or finishes where possible
  • Old sealant cut out, never sealed over
  • Colour options checked against the specified product
  • One contact handling all your sites

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Building and refurbishing in Wendens Ambo

At about 37 miles from central London, Wendens Ambo is within reach of the capital. 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 Wendens Ambo. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.

School extensions, at buildings such as Joyce Frankland Academy, normally run to the summer holidays, mastic included. Older buildings in the area around Wendens Ambo, such as Audley End House, which lies north-east of Wendens Ambo, need care when sealed: the product has to suit soft or historic materials. For contractors refurbishing units at places like Bearwalden Business Park, which lies south-west of Wendens Ambo, the mastic covers cladding panels, roller-door and window perimeters.

Your questions answered

Do you take on work at healthcare sites like Saffron Walden Community Hospital (no A&E)?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Wendens Ambo off your patch?

Not at all. Wendens Ambo is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you find out why a window is leaking?

Yes. Photos help, and you can give us a call on 01277 525 020 or email the details over to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

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.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

How long will the new sealant last?

There isn’t a single answer, 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.
