What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Crumbling edges that would give a new bead nothing sound to grip
- Cracking or settlement that calls for an engineer’s assessment
If you are not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer.

Expansion joint sealing in Greenstead
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. If you have movement joints with split or torn sealant and new sealant over old, now failing, we can help. Searching for sealant specialists in Greenstead? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Rural business units around smaller places such as Greenstead often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Advice
Leave it or put it right?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we will plan around it. In a smaller place such as Greenstead, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Signs you need expansion joint sealing in Greenstead
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again, so we check width and movement before quoting.
If one of these sounds familiar, it’s time for a closer look:
- Joints where the bead has lost adhesion
- New sealant over old, now failing
- Movement joints with split or torn sealant
- Rain penetration at brick or block movement joints
For a school such as Unity Primary Academy, playground and building joints can be done in the holidays.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents
- Is the sealant right for the movement and the substrate?
- Whether old or failed sealant will be cut out, not overlaid
Your questions answered
Can you work on a hospital site such as Colchester General Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Greenstead outside your area?
Not at all. Greenstead is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What if the joint edges are damaged?
The edges have to be sound. Where they’ve broken up, we’ll tell you they need repairing first.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Looking after the joints
After handover, a little attention goes a long way:
- Keep racking legs and heavy point loads off floor joints
- Treat a small split as a warning, not a cosmetic issue
- Inspect exposed joints once the cold weather has passed
- Put movement joints on the planned maintenance inspection round
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Working within restricted access windows
- Travel to remote or island sites
- Access and working height
- How much there is to seal
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
However big the job, these details speed things up:
- Your programme or deadline
- Specification clauses that apply
- Clear photos of the problem areas
- Asbestos survey details if the building is older
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or email us.
