Facade sealing for Fawley Bottom sites

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

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Facade sealing in Fawley Bottom, done properly

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you’re dealing with facade joints cracked through the middle and failed sealant on precast panel joints, we can put it right, on stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Fawley Bottom it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Fawley Bottom, 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Jobs in and around smaller places like Fawley Bottom are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  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.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements

Common questions from Fawley Bottom clients

Can you work on a hospital site such as Townlands Memorial 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.

Is Fawley Bottom off your patch?

No. Places such as Fawley Bottom are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Can you work in cold or wet weather?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, so we plan around the forecast.

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Mastic packages on Fawley Bottom sites

At about 36 miles from central London, Fawley Bottom is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Fawley Bottom included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

With historic properties like Stonor Park, 1.5 miles north of Fawley Bottom, in the area, refurbishment work often meets old masonry that needs compatible sealants. On a healthcare site such as Townlands Memorial Hospital, 2.6 miles to the south of Fawley Bottom, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What affects the price in Fawley Bottom

We price every job individually. The things that drive the figure:

  • Joint width, depth and condition
  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Which sealant the job calls for

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • How the joints are reached, and at what height
  • When you need the work done
  • Photos of the joints, close up and from further back
  • Any specification or named product

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, give us a call on 01277 525 020 or email us.

Different surfaces, different methods

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Specialist high-level access methods
  • Damaged frames that need replacing
  • Work on the window or framing system itself

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

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

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
