Expansion joint sealing in Colgate

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Colgate, done properly

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. If you’re dealing with sealant pulling off the joint face and hardened, cracked sealant on exposed facades, we can help, on precast concrete panel joints, cladding panel joints and podiums and floor movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Colgate is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller community and commercial buildings around Colgate have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. If others near Colgate need work, visits can be combined. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

Getting a fixed quote

Advice

What affects the price in Colgate

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Phasing around occupants
  • The site’s rules and procedures
  • How accessible the joints are
  • Location, for remote and island sites

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’ll have a fixed figure to work with.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • Any specification or named product
  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • Rough lengths or quantities, or drawings if you have them

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Questions about Colgate

Is Colgate too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on a hospital site such as Crawley 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.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

How do I request a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Do the joint edges need to be sound before sealing?

A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Does the weather affect joint sealing?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.

Where floor joints take the most wear near Colgate

Colgate sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Less than 3 miles from Colgate there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Across sites such as New House Business Centre, 1.8 miles west of Colgate, floor and movement joints can be sealed in phases so units keep working. Schools like Colgate Primary School often have long brick elevations with movement joints that age quietly. Hospital campuses such as Crawley Hospital, 3.1 miles to the north-east of Colgate, grow in stages, leaving movement joints wherever new blocks meet old.

Colgate is about 3 miles south-west of Crawley, in West Sussex. We cover commercial sites throughout Colgate. Our West Sussex coverage takes in 373 places, large and small. For work in that direction, see our Brighton page, about 18 miles away.

Postcode districts covered here: RH13 and RH12. If your site is on Forest Road, Vicarage Close and Blackhouse Road or close by, we can quote for movement joints. Nearby places we also cover include Kilnwood Vale (1 mile north), Faygate (1 mile north-west), Broadfield (2 miles north-east), Roffey (2 miles west) and Handcross (3 miles south-east) for movement joints. Bigger towns within reach include Crawley (3 miles north-east), Horsham (4 miles west), Haywards Heath (9 miles south-east), Burgess Hill (10 miles south-east), East Grinstead (11 miles east) and Storrington (14 miles south-west).

Landmarks near Colgate

Around Colgate, our work takes us to commercial buildings near The Dragon pub, Target Hill Park and Cottesmore School and the streets around them. The nearest railway station is Faygate station, about 1.3 miles north-west of the centre. Other landmarks nearby include Crawley Museum (3.4 miles north-east) and County Mall (3.4 miles north-east). Open spaces near Colgate include Tilgate Lake and Warnham LNR.

What the job involves on each surface

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints, or we visit if they don’t show enough.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

Leave it or put it right?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. For buildings around smaller places like Colgate, 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. Renewing joints in good time avoids the problem.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Why us?

  • CHAS accredited
  • Colour options checked against the specified product
  • Public liability insurance in place
  • 12-month guarantee on workmanship

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
