Expansion joint sealing in Reston
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on precast concrete panel joints, cladding panel joints and brickwork movement joints, and what we are called in for most is brittle, chalky sealant on external joints and sealant pulling off the joint face. Facilities teams, main contractors and managing agents in Reston tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In smaller places such as Reston, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
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, and tell you if edges need repairing first.
What happens if it’s left?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Around smaller places like Reston, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
- Cracking or settlement that calls for an engineer’s assessment
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.

How a job runs
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Where we can, we combine work around Reston with other jobs nearby. Tell us how flexible your dates are.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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, which is what makes a joint last.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
FAQs: Reston
Must our site in Reston stop work while the joints are done?
Usually not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.
What paperwork can you provide for a job in Reston?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you seal joints in cold or wet weather?
Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
