Expansion joint sealing for commercial buildings in Selborne
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. We work on podiums and floor movement joints, car park decks and ramps and brickwork movement joints, and the failures we’re asked to look at most are spalled or broken joint edges in floors and decks and torn sealant in brick or block movement joints. A single leaking joint is often how a building in Selborne first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places such as Selborne, 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 we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. If others near Selborne need work, visits can be combined. You’ll have a fixed quote before work starts.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Agree which areas must stay open
- Let building users know which areas are affected
- Send your site hours and access windows

Where floor joints take the most wear near Selborne
Selborne is about 46 miles from central London. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Selborne sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.
Another example is Farringdon Industrial Centre, which lies west of Selborne, where floors and yards would be done in stages around the occupiers. For a school such as Selborne Church of England Primary School, playground and building joints can be done in the holidays. Sites like Alton Community Hospital (to the north-west of Selborne) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Selborne is about 4 miles south of Alton, in Hampshire. Anywhere in GU34, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places. Sites around Portsmouth have their own page, about 21 miles away.

Selborne: questions and answers
Is Selborne too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Will you take on work at estates like Southlands Industrial Park, close to Selborne?
Yes, sites like Southlands Industrial Park are within our area, along with the rest of Selborne. Photos and a short description are enough for a first look.
How much does the work cost?
Each job is quoted on its own details. To get one, phone 01277 525 020 or send details through our quote form.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can staff carry on working while you are here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Quoting for work in Selborne
We price every job individually. The main factors are:
- Whether old sealant has to be cut out first
- The product specified
- The size and state of each joint
- Induction, permit and paperwork requirements
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- Specification clauses that apply
- Any dates the work must fit around
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or use the quote form.
Why act early in Selborne
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. Around Selborne, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

- Cladding panel joints
- Podiums and floor movement joints
- Precast concrete panel joints
- Brickwork movement joints
- Car park decks and ramps
- Blockwork control joints
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.
Brickwork and blockwork joints
Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
