Expansion joint sealing in Brook

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Brook need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Warn occupants and staff about the work

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Expansion joint sealing for commercial buildings in Brook

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied. If you are dealing with sealant peeling off one face of the joint and chipped joint edges on forklift routes, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Brook, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Brook are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Every job we finish is backed by a 12-month workmanship guarantee, in Brook as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Why act early in Brook

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 will tell you they need repairing first. Around Brook, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

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 we will put a fixed figure on it.

What you get with us

  • Public liability insurance in place
  • RAL and finish matching where the product range allows
  • 12 months’ guarantee on every job
  • Commercial sealant work since 2005

Honest limits

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Changing the joint layout or spacing of a structure
  • Concrete or masonry repairs along the arrises
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

  • Podiums and floor movement joints
  • Brickwork movement joints
  • Blockwork control joints
  • Precast concrete panel joints
  • Car park decks and ramps
  • Cladding panel joints

Expansion joint sealing around Brook: how the place shapes the job

Brook sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.

A healthcare site such as Tatchbury Mount Hospital (to the east of Brook) depends on car parks, ramps and service yards whose joints take traffic all day.

Brook is about 4 miles west of Totton, in Hampshire. Brook sits inside our coverage and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 723 places across Hampshire fall within our area, including Brook. We also cover Southampton, around 9 miles from Brook.

Just outside Brook, we also work in Wittensford (1 mile east), Cadnam (1 mile east), Minstead (2 miles south), Newbridge (2 miles north-east) and Bramshaw (2 miles north).

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Brook can form part of a wider programme across Hampshire.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Common problems we fix in Brook

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

Site and facilities staff are often the first to spot these:

  • Damp inside where a wall movement joint has failed
  • Water dripping through deck or ramp joints
  • Debris jammed in movement joints
  • Previous reseals laid over old sealant

For floors and slabs around Brook, the product is chosen for the traffic and the movement at each joint.

Questions to ask before you book

  • What site paperwork they can supply
  • How they’ll work around occupants
  • Will CSCS-carded applicators be on site?
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

What the job involves on each surface

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement, and tell you if edges need repairing first.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

FAQs: Brook

Do you take on work at healthcare sites like Tatchbury Mount 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.

Is Brook off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

What exactly is a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably and the way they’re sealed is similar.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
