Facade sealing near Crampmoor

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the quote is worked out

Before we quote, we look at:

  • Phasing around occupants
  • Whether old sealant has to be cut out first
  • Distance, for remote addresses
  • Joint width, depth and condition

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Specification clauses that apply

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or send photos by email.

How we handle facade sealing in Crampmoor

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. Most enquiries involve cladding panel joints that have opened up and hard, chalky sealant that no longer flexes, across shopfront frames, coping and flashing joints and window and door perimeters. For commercial sealant work in Crampmoor, you deal with one contact from quote to sign-off, whether it’s one building or several.

In the countryside around places like Crampmoor, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

For managing agents and facilities managers

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

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Crampmoor can sit alongside others in a wider programme across Hampshire.

Keeping the joints sound

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

  • Share access with other external trades
  • Inspect facade joints on a regular cycle
  • Report water ingress at frames as soon as it shows
  • Keep sills, gutters and drainage paths clear

Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Crampmoor need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Questions about Crampmoor

Is a hospital such as Romsey Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you cover business parks and estates near Crampmoor, such as Sleepy Hollow Business Park?

Yes. Estates, retail parks and business parks around Crampmoor, Sleepy Hollow Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

When to call us in Crampmoor

Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building.

Common reasons buildings call us in:

  • Staining on stone next to old sealant
  • Failed seals around shopfront and entrance frames
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters

New units and refits on sites such as Sleepy Hollow Business Park, 0.8 miles to the north-east of Crampmoor, need their panel and perimeter joints sealed to the specification.

Choosing a commercial sealant contractor

Contractors’ notes for Crampmoor

Central London is about 68 miles from Crampmoor. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Crampmoor is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

Extensions at sites like Romsey Hospital, 1.4 miles to the south-west of Crampmoor, typically sit beside working departments, and the mastic follows strict access rules.
