Why it’s worth doing now in Sandridge
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. In a small place like Sandridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

About our fire rated sealant in Sandridge
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on flats & HMOs, linear gaps and pipe & cable gaps, and common reasons people get in touch are gaps flagged on a fire risk assessment and open joints along the top of partitions.
For a small place like Sandridge, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Do you need fire rated sealant in Sandridge?
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
The problems people generally mention when they call are:
- Gaps filled with a product that is not fire-rated
- Damaged fire sealant left by other trades
- Holes left by a change of layout
- Sealant items on a fire risk assessment action list
Rented homes near St Albans station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Questions to ask before booking
- How hidden problems are handled
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- Is VAT in the price?
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sandridge: your questions answered
Is Sandridge in your area for fire rated sealant?
Yes, Sandridge is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is Sandridge within the area you cover?
Yes, Sandridge is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will you assess my building’s fire safety?
No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
What information do you need?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
What fire rating will the seal have?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
Surface by surface
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Store the list of sealed gaps with your building paperwork
- Take photos of fire stopping before ceilings or boxing go back
- Report cracked or damaged seals as soon as you notice them
- Ask which product was used before you paint
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

What fire rated sealant looks like in Sandridge
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a church, hall or community building such as St Leonard's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Sandridge School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
