FAQs: Brickendon

Is Brickendon too far out for you?

No. Places such as Brickendon are covered as much as the big 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 work at a site such as Mimram Road Industrial Estate, by Brickendon?

Yes. Our area takes in Brickendon and its surroundings, with estates and business parks such as Mimram Road Industrial Estate included. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Expansion joint sealing in Brickendon, done properly

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you have torn sealant in brick or block movement joints and new sealant over old, now failing, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Brickendon, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Brickendon are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Brickendon can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space

Common problems we fix in Brickendon

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.

Look out for the following:

  • Previous reseals laid over old sealant
  • Joints where the bead has lost adhesion
  • Rain penetration at brick or block movement joints
  • Hardened, cracked sealant on exposed facades

Hospitals like Hertford County Hospital (to the north of Brickendon) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Choosing a commercial sealant contractor

Expansion joint sealing in Brickendon: the local picture

Brickendon has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

A campus such as University of Hertfordshire (to the west of Brickendon) has long runs of movement joint in its buildings, decks and paving. On industrial estates such as Mimram Road Industrial Estate, which lies north of Brickendon, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Brickendon is about 3 miles west of Hoddesdon, in Hertfordshire.

Should maintenance staff do it?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Quoting for work in Brickendon

A fixed quote reflects the actual work. It allows for:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Working within restricted access windows
  • Any access equipment needed

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why deal with it now?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed. Around Brickendon, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
