Expansion joint sealing for Newnham sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Cost factors for movement joints
Before we quote, we look at:
- The total length or number of joints
- Any access equipment needed
- Working within restricted access windows
- Which sealant the job calls for
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.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
- The product your specification calls for

How we handle expansion joint sealing in Newnham
If you need expansion joint sealing in Newnham, start with photos and joint lengths. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. You can also speak to us on 01277 525 020 or email us to talk the joints through. Most enquiries involve water dripping through deck or ramp joints and chipped joint edges on forklift routes, across cladding panel joints, brickwork movement joints and precast concrete panel joints. A specialist sealant contractor works differently from a general builder: in Newnham, that means joint design, primers and backing rod as standard.
Around smaller places such as Newnham, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Newnham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Let building users know which areas are affected

When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Movement on a scale no sealant is meant to absorb
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Surfaces we seal
- Car park decks and ramps
- Blockwork control joints
- Cladding panel joints
- Podiums and floor movement joints
- Brickwork movement joints
- Precast concrete panel joints
Questions we are asked in Newnham
Is Newnham too small for you to travel to?
No. Places such as Newnham are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Is hospital work, at somewhere like Basingstoke and North Hampshire Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
What timescale should we allow for resealing expansion joints?
Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote along with the phasing plan.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.

Traffic, movement and joints around Newnham
Rainfall across the South East, Newnham included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Newnham is about 41 miles from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.
Hospital campuses such as Basingstoke and North Hampshire Hospital, 5.2 miles west of Newnham, grow in stages, leaving movement joints wherever new blocks meet old. At places like Hatch Industrial Park, 2.2 miles south-west of Newnham, joints are sealed a section at a time so operations carry on.
Newnham is about 5 miles east of Basingstoke, in Hampshire. Commercial clients in Newnham can call on us for movement joints. Newnham is one of 723 places we cover in Hampshire for movement joints. We also cover Reading, around 12 miles from Newnham.

Local landmarks in Newnham

When to call us in Newnham
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way.
Typical triggers for a call:
- Joints packed with grit and debris
- Spalled or broken joint edges in floors and decks
- Joints where the bead has lost adhesion
- Damp inside where a wall movement joint has failed
For buildings at a park such as Optrex Business Centre, which lies north of Newnham, brick and panel movement joints are easy to forget until one leaks.

Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
