Facade sealing in Fernhurst

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

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Facade sealing in Fernhurst

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you are dealing with hard, chalky sealant that no longer flexes and perimeter joints where frames meet the structure, we can put it right, whatever the surface. For commercial sealant work in Fernhurst, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a site near Fernhurst, 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 photos and the programme and we’ll quote to suit.

Whoever the client is, the cover is the same: 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.

New build and refits around Fernhurst

At about 41 miles from central London, Fernhurst is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

New wings at hospitals like Holy Cross Hospital (to the north of Fernhurst) bring long runs of window and panel joints to seal. With historic properties like Cowdray House (4.3 miles south of Fernhurst) in the area, refurbishment work often meets old masonry that needs compatible sealants. New units and refits on sites such as Hurstfold Industrial Estate, 1.3 miles south-east of Fernhurst, need their panel and perimeter joints sealed to the specification.

Fernhurst is about 10 miles east of Petersfield, in West Sussex. Across the GU27 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 373 places in West Sussex, from busy centres to rural villages. There’s a separate page for Portsmouth, about 23 miles away.

Different surfaces, different methods

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface.

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 rather than the system it surrounds.

Cost factors for facade joints

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Travel to remote or island sites
  • How much there is to seal
  • Whether old sealant has to be cut out first
  • Access and working height

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

A few photographs plus some basic facts will normally do. It helps to include:

  • The product your specification calls for
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • Access details, including height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why deal with it now?

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Halls, stores and units around places like Fernhurst may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Damaged frames that need replacing

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think.

Surfaces we seal

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

Your questions answered

Is Fernhurst too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you take on work at healthcare sites like Holy Cross Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you install glazing systems?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Rural sites near Fernhurst may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  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

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed
