Do you need fire stopping in Chartwell Green?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.
Typical triggers for a call:
- Builders’ foam or ordinary silicone in compartment walls
- Snag lists that include open service penetrations
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
At a college such as Itchen College, 1.5 miles to the south of Chartwell Green, checking penetration seals after summer M&E works is good practice.

About our fire stopping in Chartwell Green
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with openings left by services added after handover and improvised or mixed-product fire seals, we can help, on service gaps in risers, linear gaps at wall heads and joints between fire-resisting walls and floors alike. Looking for mastic applicators who cover Chartwell Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Converted and extended buildings around places like Chartwell Green can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Cost factors for service penetrations
Your fixed quote is built from the real scope. It allows for:
- Which sealant the job calls for
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Sending details for a quote
However big the job, these details speed things up:
- What the building is and how it’s used
- Anything awkward about access or site hours
- The product your specification calls for
- The site address and postcode
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email the details over.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Work in places the size of Chartwell Green is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
Quotes
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Your questions answered
Do you cover business parks and estates near Chartwell Green, such as Seddul Bahr Industrial Estate?
Yes. We cover Chartwell Green and the area around it, including industrial estates, business parks and retail parks such as Seddul Bahr Industrial Estate. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you seal penetrations in a hotel in Chartwell Green after a refit?
Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Service penetrations in Chartwell Green buildings
Chartwell Green lies roughly 67 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. Chartwell Green has five care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
Campus buildings at universities such as University of Southampton, 2.2 miles west of Chartwell Green, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. On estates like Seddul Bahr Industrial Estate, 1.4 miles to the north-east of Chartwell Green, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Keeping the joints sound
For the best life from the joints:
- Keep general-purpose fillers away from compartment walls
- Include service cupboards in routine inspections
- Record which product was used where
- Ask the designer to confirm details early on refits
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
