Coloured sealant in Caversham Heights, done properly

A coloured bead has to perform like any other sealant. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only, with no shortcuts because it’s decorative. Careful masking keeps the edges crisp. If you have weathered sealant that no longer matches and old colour-matched joints lifting at the edges, we can help, whatever the surface. One point of contact handles commercial sealant work in Caversham Heights from the first photos to the final walk-round, whether it’s one building or several.

Sealant jobs for businesses in a place the size of Caversham Heights are often best grouped: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down.

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.

Common questions from Caversham Heights clients

Is Caversham Heights too small for you to travel to?

Not at all. Caversham Heights is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is The Station Shopping Park, near Caversham Heights, within your area?

Yes. We cover Caversham Heights and the area around it, including industrial estates, business parks and retail parks such as The Station Shopping Park. Send details of the unit and the work through our quote form for a quick quote.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Is coloured sealant weaker than white?

The product type decides performance, not the colour. The joint gets the product it needs, in a colour from that product’s range.

Can we specify the colour by RAL number?

Yes. Give us the RAL reference and we’ll check it against the product’s range. We will tell you which colour is closest at quote stage.

Does coloured sealant change colour outdoors?

Exposed sealant can change in appearance over the years. UV and grime can soften or alter the colour.

Can the building stay open while you work?

Usually, yes. Phased work can be planned so areas stay in use.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. What matters most for a job in Caversham Heights is a clear list of what needs doing. A fixed quote follows.

  1. We confirm the product the joint needs before talking about colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We take out the existing bead, clean the joints and fit backing.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Before we start on site

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

How the job changes by surface

Paintable sealants

Some joints are better sealed with a paintable product and decorated. It depends on movement and the specification, as paint can crack on a moving joint.

Office fit-outs

Partition frames and joinery are often in a set colour. We choose sealant colours to suit.

Why deal with it now?

Agreeing the colour before work starts avoids paying twice. A sample takes little time compared with replacing joints in the wrong colour. In a smaller place such as Caversham Heights, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sealant on show in Caversham Heights’s commercial buildings

When to call us in Caversham Heights

When frames are recoated or a space is rebranded, the old joints may no longer suit. Refurbishments and rebrands often bring a new colour scheme.

It’s worth sending us details if you spot any of the following:

  • Marked sealant in hotel bathrooms
  • Coloured joints that have cracked with movement
  • Hotel refurbishments with a set colour scheme
  • Patch repairs in several different colours

If you look after units at a retail site such as The Station Shopping Park, which lies south-east of Caversham Heights, shopfront perimeters and shop-fit joints are where a matched colour shows.

What to look for in a quote

  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it
  • Who will actually carry out the work
  • How long is the guarantee, and what does it include?

Our contractor checklist

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
