Mastic sealing in Durley Street, done properly
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have no planned programme for sealant and brittle perimeter mastic across a building, we can help, whatever the surface. A single leaking joint is often how a building in Durley Street first comes to us: we look at the rest while we are there and tell you what we find.
In and around smaller places like Durley Street, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need mastic sealing in Durley Street
Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Things that normally lead to an enquiry:
- Complaints coming in block by block
- Old repairs sealed over failed mastic
- Estate-wide sealant that is simply worn out
- Damaged joints in communal entrances and corridors
Buildings close to stations like Hedge End station, 2.8 miles to the south-west of Durley Street, are often flats over shops, with frame mastic to keep sound.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
- How joint depth will be controlled
- The named product and why it was chosen

Planned mastic for Durley Street portfolios
Central London is about 62 miles from Durley Street. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Durley Street included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Property owners at sites such as Deer Park Farm Industrial Estate (to the west of Durley Street) can have mastic renewed between lettings. Site managers at schools like Wyvern Technology College can fit frame mastic into the summer works.

Should maintenance staff do it?
For most general trades, sealant is a sideline. 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.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Looking after the joints
To get the most from the new sealant:
- Track which buildings were done and when
- Group repairs into a planned programme
- Ask residents or tenants to report leaks and draughts early
- Check the asbestos register before any old mastic is disturbed
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Asbestos-containing sealant, which we don’t remove
- Broken glass or failed sealed units
- Leaks through the frame itself rather than the perimeter
If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.
What we seal
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Balcony and threshold joints
- Communal entrances and stairwells
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Any access equipment needed
- The product specified
- Quantities, in metres or numbers
- Location, for remote and island sites
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Whether an asbestos survey exists
- Access details, including height
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Questions about Durley Street
Do you work for managing agents with blocks near Hedge End station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Do you cover business parks and estates near Durley Street, such as Deer Park Farm Industrial Estate?
Yes. Estates, retail parks and business parks around Durley Street, Deer Park Farm Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
