Need expansion joint sealing in Dudswell?
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Crumbling edges that would give a new bead nothing sound to grip
- Waterproofing layers buried beneath the sealant
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.
Surfaces we seal
- Brickwork movement joints
- Cladding panel joints
- Podiums and floor movement joints
- Car park decks and ramps
- Blockwork control joints
- Precast concrete panel joints
Expansion joint sealing in Dudswell
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. We work on precast concrete panel joints, cladding panel joints and brickwork movement joints, and the failures we are asked to look at most are spalled or broken joint edges in floors and decks and debris jammed in movement joints. Most enquiries from Dudswell start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Halls, schools and small commercial buildings near places like Dudswell have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Dudswell
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Whether the work must be split into stages
- Site requirements such as inductions and permits
- Location, for remote and island sites
- Quantities, in metres or numbers
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
A few photographs plus some basic facts will normally do. It helps to include:
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- When you need the work done
- Specification clauses that apply
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email a schedule or drawings.
Do you need expansion joint sealing in Dudswell?
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. The product has to be suited to the traffic.
Any of the following is a good reason to get the joints checked over:
- Torn sealant in brick or block movement joints
- Brittle, chalky sealant on external joints
- Sealant peeling off one face of the joint
- Rain penetration at brick or block movement joints
On industrial estates such as Northbridge Road Industrial Estate (1 mile south-east of Dudswell), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?
- Can the work be phased to keep areas open?
- Whether primer will be used where the manufacturer specifies it
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Dudswell need work, visits can be combined. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- 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.
- 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.
What we need from you
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions
Request a 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.
Advice
Different surfaces, different methods
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

Questions about Dudswell
Is a smaller place like Dudswell outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you take on a job at a hospital such as Hemel Hempstead Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How much does the work cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Can you work while the building is occupied?
Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Can you seal joints in cold or wet weather?
Sealing onto a damp surface leads to adhesion failure, so external work waits for suitable conditions. We agree a revised date with you.
Is movement joint sealing guaranteed?
Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
