About our mastic sealing in Tapnage
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you are dealing with cracked, hardened mastic round windows on a block and damaged joints in communal entrances and corridors, we can put it right, whatever the surface. A single leaking joint is often how a building in Tapnage first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as Tapnage tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Block-wide mastic in Tapnage
At about 64 miles from central London, Tapnage is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property. Tapnage is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Site managers at schools like The Henry Cort Community College can fit frame mastic into the summer works. Buildings close to stations like Swanwick station (to the south-west of Tapnage) are often flats over shops, with frame mastic to keep sound.

What else we do in Tapnage
Owners, agents and contractors
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When to call us in Tapnage
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.
It’s worth sending us details if you spot any of the following:
- Estate-wide sealant that is simply worn out
- Old repairs sealed over failed mastic
- Communal area joints that look neglected
- Leaks at window and door perimeters
For owners of several units at places like Knowle Village Business Park, 0.7 miles south-east of Tapnage, one programme can deal with frame and external mastic across the lot.
Comparing quotes
- Is the sealant right for the movement and the substrate?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
Questions about Tapnage
Will you take on a block within reach of Swanwick station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Can you work at a site such as Knowle Village Business Park, by Tapnage?
Yes, sites like Knowle Village Business Park are within our area, along with the rest of Tapnage. A few photos and the unit address let us price the work.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you cover Tapnage?
Yes. Tapnage is in our area and the rest of Hampshire. For a quote, call 01277 525 020 or email us.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
Can you send RAMS and CSCS details before starting?
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.
Looking after the joints
To get the most from the new sealant:
- Protect low-level joints in entrances
- Start inspections with the most exposed faces
- Keep a record of when each building was resealed
- Make mastic part of routine maintenance checks
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
Cost factors for mastic joints
Each job is priced on its own details. The things that drive the figure:
- Access and working height
- The site’s rules and procedures
- How much existing material needs removing
- Travel to remote or island sites
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email the details over.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Tapnage may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Move anything stored against the joints
- Send your site hours and access windows
