From enquiry to sign-off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Martin may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- 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.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Let building users know which areas are affected
- Agree which areas must stay open
- Explain the parking and delivery arrangements

Advice
How we handle expansion joint sealing in Martin
A movement joint only works while its seal does. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. Site teams most often ask us about water getting into the wall through a failed joint and torn sealant in brick or block movement joints, across precast concrete panel joints, cladding panel joints and podiums and floor movement joints. Whoever orders the work in Martin, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller community and commercial buildings around Martin have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions we’re asked in Martin
What paperwork can you provide for a job in Martin?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Will our site in Martin have to close for joint sealing?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
What happens if it rains on the day?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What exactly is a movement joint?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Changing the joint layout or spacing of a structure
- Cracking or settlement that calls for an engineer’s assessment
- Leaks coming from the membrane rather than the joint seal
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Floors, slabs and movement joints in Martin
The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
For floors and slabs around Martin, the product is chosen for the traffic and the movement at each joint. Around Martin, open joints collect water and debris, and the arrises are the next to go.

Different surfaces, different methods
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
What happens if it’s left?
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. For buildings around smaller places like Martin, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
- Note which joints were done, when, and with what
- Plan racking layouts so feet don’t land on a joint
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
