Mastic sealing in Hannington
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. Most enquiries involve damaged joints in communal entrances and corridors and repeated reactive repairs to the same buildings, on communal kitchens and washrooms, external wall and movement joints and balcony and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hannington is the same: the right product in a properly prepared joint.
Around smaller places like Hannington, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Block-wide mastic in Hannington
Central London is about 51 miles from Hannington. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide. Hannington sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.
Hannington is about 5 miles south-west of Tadley, in Hampshire. Across the RG26 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Do you need mastic sealing in Hannington?
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.
Site and facilities staff are often the first to spot these:
- Patchy repairs in mismatched sealant
- Repeated reactive repairs to the same buildings
- Water getting in round frames after rain
- Communal area joints that look neglected
Buildings close to stations like Overton station (to the south-west of Hannington) are often flats over shops, with frame mastic to keep sound.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Their public liability cover
- How the existing material will be dealt with
- How long is the guarantee, and what does it include?
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Asbestos-containing sealant, which we don’t remove
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think before you book.
Surfaces we seal
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
- Window and door perimeters on blocks
Why deal with it now?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Around Hannington, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What else we do in Hannington
Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Questions we’re asked in Hannington
Can you quote for a block close to Overton station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Do you take on block-wide or estate-wide mastic work in Hannington?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so there are no surprises.
