How we handle facade sealing in Fernham
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. We work on cladding panel joints, stone and brick facade joints and window and door perimeters, and what we’re called in for most is cladding panel joints that have opened up and water coming in around window frames. A single leaking joint is often how a building in Fernham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Fernham, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
Every job we finish is backed by a 12-month workmanship guarantee, in Fernham as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Fernham need work, visits can be combined. You will have a fixed quote before work starts.

Other services in Fernham
Different surfaces, different methods
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Building and refurbishing in Fernham
At about 64 miles from central London, Fernham is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Fernham sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
For contractors refurbishing units at places like Faringdon Business Park, 1.4 miles north-west of Fernham, the mastic covers cladding panels, roller-door and window perimeters. Extensions at sites like Faringdon Day Hospital, 2.2 miles to the north of Fernham, usually sit beside working departments, and the mastic follows strict access rules. When a school such as Faringdon Community College is extended or refurbished, the mastic package is often squeezed into the holidays.

Why deal with it now?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Converted and older buildings near places like Fernham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

How long does a job like this take?
That varies with the scale of the job, but the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
How is access to upper-level joints handled?
Access is planned with you before we quote. Let us know what access is in place or planned, and we will price the work around it.
What do you charge?

Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
