Expansion joint sealing near Well Head

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Avoid parking heavy plant or pallets on joint lines
  • Reopen bays and walkways only after the stated cure time
  • Include every elevation and deck joint in periodic inspections
  • Record the sealant used and the date in the O&M file

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.

How we handle expansion joint sealing in Well Head

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Well Head. If you have brittle, chalky sealant on external joints and expansion joints filled with dirt and stones, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Well Head, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Well Head 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What we are called out for in Well Head

When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.

Things that typically lead to an enquiry:

  • Hardened, cracked sealant on exposed facades
  • Sealant peeling off one face of the joint
  • Water dripping through deck or ramp joints
  • Water getting into the wall through a failed joint

On industrial estates such as Wingham Industrial Estate, which lies north-west of Well Head, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

How to choose a sealant contractor

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Why act early in Well Head

Resealing is typically the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. For buildings around smaller places like Well Head, 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 price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Why us?

  • CHAS accredited
  • 12 months’ guarantee on every job
  • Products installed to the manufacturer’s instructions
  • Public liability insurance in place

Common questions from Well Head clients

Is Well Head off your patch?

No. Places such as Well Head are covered as much as the big towns. Our area covers London and the South East counties. Send photographs 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 St Martins Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Why do our movement joints keep failing?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.

Can staff carry on working while you’re here?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Do you use silicone or polyurethane in movement joints?

The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What the job involves on each surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. For work around Well Head, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Move anything stored against the joints
  • Have the specification and drawings to hand
