Overton: questions and answers
What paperwork can you provide for a job in Overton?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Do we have to stop operations in Overton while the joints are sealed?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.
What sealant do you use in movement joints?
The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you guarantee expansion joint work?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a site in Overton, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Arrange parking or a loading space
- Send your site hours and access windows
- Share the asbestos register for older buildings

How the job changes by surface
Cladding panel joints
We confirm what access is in place before pricing. Close-up photos help us judge the joints.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in.
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Why act early in Overton
Resealing is normally the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why appoint us
- A Constructionline member, so easy to vet
- RAL and finish matching where the product range allows
- Health and safety: CHAS accredited
- Work carried out by CSCS-carded applicators

Warehouse floors and decks around Overton
Overton sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Overton lies roughly 53 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.
Schools such as Overton Church of England Primary School have movement joints in their walls and floors that are easy to overlook.
Overton is about 7 miles west of Basingstoke, in Hampshire. Across the RG25 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Site staff or a sealant specialist?
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.
Putting right a botched joint often costs more than sealing it well at the start, 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.

Common problems we fix in Overton
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.
Site and facilities staff are often the first to spot these:
- Joints packed with grit and debris
- Expansion joints split through the centre of the bead
- Water getting into the wall through a failed joint
- New sealant over old, now failing
Around Overton, each joint gets a filler or sealant matched to what crosses it and how much it moves.
Questions to ask before you book
- Proof of insurance
- Whether their applicators hold CSCS cards
- How long is the guarantee, and what does it include?
- Is the sealant right for the movement and the substrate?
