Sealant work in Knights Enham for main contractors, managing agents and facilities managers: fire-rated and intumescent sealing of service penetrations and linear gaps, with a fixed quote first.

Fire stopping for Knights Enham sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Fire stopping in Knights Enham
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you have unsealed penetrations discovered above suspended ceilings and unsealed joints where partitions meet the slab, we can put it right. Most enquiries from Knights Enham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Barn and farm-building conversions near places like Knights Enham often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we will arrange a return visit.

After the work
To get the most from the new sealant:
- Put resealing into every M&E and fit-out package
- Look above ceilings when tiles are lifted for other jobs
- Report damaged or disturbed seals as soon as they’re spotted
- Get seals inspected before ceilings and boxing close
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
What affects the price in Knights Enham
A fixed quote reflects the actual work. It takes account of:
- The product specified
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Any access equipment needed
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Any dates the work must fit around
- Whether an asbestos survey exists
- Access details, including height
- What the building is and how it’s used
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Penetration seals near Knights Enham
There are several hotels within about 2 miles of Knights Enham. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a hospital such as Andover Hospital (Grounds), which lies south-west of Knights Enham, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Colleges such as Andover College (1.4 miles south of Knights Enham) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Local landmarks in Knights Enham

A little further out are Finkley Down Farm Museum (1.2 miles south-east) and Andover War Memorial Hospital (1.3 miles south-west). For a walk, there’s Mill Lake and Anton Lakes.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Common questions from Knights Enham clients
Is Knights Enham 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. Where we can, we group nearby jobs to make the most of each trip.
Can work at a site such as Andover College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Knights Enham 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 ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Share your working hours and any access restrictions
