Common questions from Colwood clients
Is Crosspot Industrial Estate, near Colwood, within your area?
Yes. Our area takes in Colwood and its surroundings, with estates and business parks such as Crosspot Industrial Estate included. Photos and a short description are enough for a first look.
Is a smaller place like Colwood outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
Are expansion joints and movement joints the same thing?
The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped.
Is colour matching possible?
That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do the joint edges need to be sound before sealing?
Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.

Less than 3 miles from Colwood there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

How the job changes by surface
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

What else we do in Colwood
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. If others near Colwood need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Let us know about inductions and permits
- Point out parking and an unloading spot

Related advice
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- A joint that has to be widened or re-detailed before it can work
- Crumbling edges that would give a new bead nothing sound to grip
- Waterproofing layers buried beneath the sealant
If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.

When to call us in Colwood
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.
Look out for the following:
- Spalled or broken joint edges in floors and decks
- Water getting into the wall through a failed joint
- New sealant over old, now failing
- Car park joints leaking onto vehicles below
Sites like The Dene Hospital, 3.8 miles to the south-east of Colwood, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
What your quote should include
- Their public liability cover
- Do they follow the manufacturer’s priming guidance?
- Will RAMS and insurance details be available?
- How joint depth will be controlled
How the quote is worked out
We price every job individually. The things that drive the figure:
- Removal of failed or old sealant
- Any access equipment needed
- Whether the work must be split into stages
- Distance, for remote addresses
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.
