What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
- Masonry that has broken away beside the joint
Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly.
What we seal
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Balcony and threshold joints
Mastic sealing for commercial buildings in Picket Twenty
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’ll confirm the colours available for the specified product. We work on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints, and the failures we’re asked to look at most are draughts at frames across a block and water getting in round frames after rain. Most enquiries from Picket Twenty 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.
In and around smaller places like Picket Twenty, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Looking after buildings in and around Picket Twenty
Picket Twenty is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. At about 62 miles from central London, Picket Twenty is within reach of the capital. 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.
Landlords with units on estates such as Walworth Business Park (to the north of Picket Twenty) can bring frame, door and external mastic across several units into one programme. If you look after a block within reach of Andover station (1.8 miles west of Picket Twenty), frame and balcony mastic can be renewed on one programme. Older community buildings, United Reformed Church among them, often have frames of mixed ages whose mastic varies.
Picket Twenty is about 1 mile east of Andover, in Hampshire. Businesses, contractors and managing agents in Picket Twenty can call on us for mastic joints. Our Hampshire coverage takes in 723 places, large and small. Sites around Southampton have their own page, about 20 miles away.

Quoting for work in Picket Twenty
We price every job individually. The main factors are:
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Which sealant the job calls for
- How accessible the joints are
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
We can often quote from photographs and a few details. It helps to include:
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
- The postcode of the building
- Any specification or named product
Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or email us.
Building owners, agents and FMs in Picket Twenty
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. For buildings around smaller places like Picket Twenty, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Why appoint us
- CHAS accredited
- One phone line for London, the South East and Scotland

Your questions answered
Does your area include sites such as Walworth Business Park, near Picket Twenty?
Yes. Estates, retail parks and business parks around Picket Twenty, Walworth Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Will you take on a block within reach of Andover station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Maintenance after handover
To get the most from the new sealant:
- Include mastic in your cyclical inspections
- Track which buildings were done and when
- Prioritise elevations facing the weather
- Check the asbestos register before any old mastic is disturbed
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
