What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Render or concrete edges that have broken away
  • Installing or repairing glazing systems
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.

What we seal

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

How we handle facade sealing in West Marden

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you are dealing with old perimeter mastic that has dried out and cladding panel joints that have opened up, we can put it right. For commercial sealant work in West Marden, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Construction in and around smaller places such as West Marden 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.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we will come back to it.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around West Marden can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Make sure the joints can be reached
  • Let us know about inductions and permits
  • Send any specification or drawings in advance

New build and refits around West Marden

Rainfall across the South East, West Marden 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. West Marden is about 53 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Historic houses such as Uppark (to the north of West Marden) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors at a school such as Compton and Up Marden CofE Primary School, sealing has to be finished before term starts. New wings at hospitals like Havant War Memorial Hospital, 5.6 miles south-west of West Marden, bring long runs of window and panel joints to seal.

West Marden is about 5 miles east of Horndean, in West Sussex. We cover West Marden, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our West Sussex coverage takes in 373 places, large and small. Our Portsmouth page has more on work in that area.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Confirm the survey covers external sealants in older buildings
  • Keep pressure washers away from fresh sealant
  • Plan facade sealing alongside redecoration
  • Report water ingress at frames as soon as it shows

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.

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

When to bring in a 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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Questions we are asked in West Marden

Would you work within a site like Havant War Memorial Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can the mastic package for our job in West Marden follow the site programme?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

What will the job cost?

Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or send details through our quote form with a description of the work.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Can the sealant be colour-matched?

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

How the quote is worked out

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • How much existing material needs removing
  • Any access equipment needed

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings
  • Any specification or named product
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email drawings and photos.

Surface by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

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.
