Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sets the cost
The price varies from site to site. It mainly depends on:
- The site’s rules and procedures
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
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.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Whether an asbestos survey exists
- The postcode of the building
- Your programme or deadline
- A wide shot and a close-up of the area
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Different surfaces, different methods
Brickwork and blockwork joints
Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Carpenders Park, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Flag any permit to work we’ll need
- Share your working hours and any access restrictions

Questions we’re asked in Carpenders Park
Do you take on work at healthcare sites like Watford General Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Arches Retail Park, near Carpenders Park?
Yes. Our area takes in Carpenders Park and its surroundings, with estates and business parks such as Arches Retail Park included. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can a joint be sealed if the edges are broken?
The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first.
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.

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What do you charge?
Each job is quoted on its own details. To get one, call 01277 525 020 or email drawings and photos.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Looking after the joints
After handover, a little attention goes a long way:
- Note which joints were done, when, and with what
- Look over external and deck joints after a hard winter
- Keep scrapers and ploughs from dragging across joint sealant
- Reopen bays and walkways only after the stated cure time
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it. A routine sweep is the simplest protection.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Movement on a scale no sealant is meant to absorb
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
