Coloured sealant in The Folly, done properly
Colour is often written into the specification, by RAL reference or by matching a sample. Standard sealant ranges cover many colours, and we’ll confirm the colours available for the specified product. We don’t promise an exact custom match, but we’ll show you the closest options. If you’re dealing with hotel refurbishments with a set colour scheme and standard-colour sealant spoiling a high-end finish, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in The Folly is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job in a smaller place like The Folly is usually a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.
What our 12-month guarantee covers is the way we did the job: 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.

Our process
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. Rural sites near The Folly may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First we agree which sealant type the joint needs.
- We compare the target colour with the colours available.
- You approve the colour, on site if it’s critical.
- The existing bead comes out, then faces are cleaned and backed.
- We mask, seal and tool to a clean line.
- Masking comes off and the work is checked with you.
Before we start on site
- Point out parking and an unloading spot
- Confirm the product named in the specification
- Send your site hours and access windows

Related advice
Site staff or a sealant specialist?
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Questions we are asked in The Folly
Will you take on work at estates like Southdown Industrial Estate, close to The Folly?
Yes. We cover The Folly and the area around it, including industrial estates, business parks and retail parks such as Southdown Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Can the sealant on our The Folly premises match the finishes?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
What we are called out for in The Folly
Sometimes the wrong colour went in at the start. The joint may work perfectly but look out of place, and a client or designer asks for it to be redone.
Site and facilities staff are often the first to spot these:
- Joints that need to match a new RAL frame colour
- Untidy coloured beads with ragged edges
- Old sealant that has yellowed, darkened or faded
- Shop fits that need consistent sealant colours across sites
Industrial estates such as Southdown Industrial Estate, 1.8 miles west of The Folly, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Why it’s worth doing now in The Folly
Leaving a failed coloured joint risks more than appearance. Water through a split seal can stain or damage the surfaces next to it, so it’s worth fixing early. Halls, stores and units around places like The Folly may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us

What affects the price in The Folly
To price the job, we consider:
- The total length or number of joints
- Location, for remote and island sites
- Joint width, depth and condition
- Whether the work must be split into stages
We don’t publish prices, since every building and every scope is different. Call for a quote.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Drawings or a marked-up plan, if available
- The product your specification calls for
- Whether the building will be occupied during the work
- How the joints are reached, and at what height
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, ring 01277 525 020 or email a schedule or drawings.
Keeping the joints sound
Once the work is signed off, these steps help:
- Use one colour standard across multi-site work
- Keep harsh solvents away from visible joints
- Keep the area clear while the sealant cures
- Ask contractors to check the colour before resealing
If other trades disturb a coloured joint, ask them to tell you rather than patch it. Wrong-colour patches are obvious, undoing the look you paid for.
Ask for a trial bead on high-profile areas. A sample in real light shows how it will look.
