Cavity Wall Insulation Andover
Cavity wall insulation for Andover homeowners
At Loft Insulation Specialists, we help Andover homeowners cut heating bills and stay warmer with professionally installed Superbead EPS cavity wall insulation. With over 40 years of experience across Hampshire, we know the town’s housing well – from the 1960s overspill estates around Floral Way, Cricketers Way and River Way to newer developments like Augusta Park.
Up to 35% of your home’s heat can escape through uninsulated cavity walls. Our Superbead system injects bonded, water-repellent expanded polystyrene beads under pressure to fill the cavity completely and lock warmth in. Andover grew rapidly after 1960, so most of its housing is cavity-walled and suits a fill; if you live in the older solid-walled core around Marlborough Street or Church Close, cavity insulation won’t apply – and we’ll tell you that honestly at survey rather than sell you the wrong product.
Sitting high on open chalk downland at the edge of Salisbury Plain, the town gets its share of wind-driven rain, so we check exposure and wall condition before recommending a fill. Every job comes with a free, no-obligation survey and a fixed-price quote – no high-pressure sales, no jargon, just straightforward advice from a local team rated 5.0 on Google and Checkatrade.
How Andover homeowners benefit from Cavity Wall Insulation
Before we inject a single bead in Andover, we run through five key checks – from build era to downland exposure. Together they tell us whether your home suits Superbead and make sure the fill keeps performing on these exposed chalk hills for decades to come.
Build era and wall type in Andover
Cavity brick walls became standard from the 1920s, and nearly all of Andover’s growth came later – the town trebled in size between 1960 and 1981 as a London overspill town, so estates from Floral Way through to River Way and Admiral Way sit squarely in the cavity era, with two leaves of brick separated by a 50mm-plus gap. The pre-1920 core is solid-walled brick and flint, which needs a different approach – we confirm which you have at survey.
What the borescope shows us
Before quoting, we pass a borescope camera into the cavity through a small hole to see what’s really there. On a 1960s estate home this can reveal rubble, damp or a part-filled cavity from an earlier scheme; on newer properties it confirms whether insulation is already in place. We verify width and condition before recommending anything.
Exposure on Andover’s chalk downland
Andover sits at around 90m on open chalk downland at the eastern edge of Salisbury Plain, catching roughly 805mm of rain across 124 wet days a year – more exposed than a sheltered valley town. We assess each elevation for wind-driven rain before any fill, and Superbead’s bonded, water-repellent beads are built to keep moisture out on the windward walls.
How Superbead works in Andover homes
Superbead suits Andover’s cavity-walled stock – the 1960s and 1970s London-overspill semis and terraces around Floral Way, Cricketers Way and Admiral Way, built when the town trebled in size. Millions of tiny EPS beads are injected under pressure to fill the cavity completely, then bond together with a water-repellent additive to form a seamless, breathable thermal barrier that won’t slump or soak up moisture.

How our Cavity Wall Insulation service works in Andover
Take a look below to find out how our Cavity Wall Insulation service works in Andover,
- 1
Book your free Andover survey
Book your free Andover cavity wall survey and we'll carry out a borescope inspection to confirm suitability for Superbead insulation.
Our surveyor inspects the cavity itself with a borescope camera, checking width and condition and looking for rubble, damp or any earlier fill.
We then tell you plainly whether Superbead suits your walls – and if it doesn’t, as in the solid-walled cottages near the town centre, we’ll point you towards the right alternative instead.
- 2
Receive your fixed price quote
Your quote is fixed before any work begins, priced on wall area, access and the number of injection points your home needs – nothing added later.
Approved for ECO4 or Great British Insulation Scheme funding? We install under both schemes – worth checking, as around a third of Andover homes sit in council tax bands A–B.
One price covers everything: labour, Superbead materials, drilling and sealing, waste handling and your 10-year IAA-backed guarantee.

Professional Cavity Wall Insulation service provided
Most cavity wall insulation installs in Andover are completed in 2-4 hours, with all work carried out from outside your home.
All the work happens at the outer face of your walls: we drill discreet holes in the mortar joints, inject Superbead under controlled pressure, then make each hole good with colour-matched mortar.
Once the fill is complete, we check every elevation, walk you round the finished work and hand over your 10-year IAA guarantee paperwork before leaving.
How much does Cavity Wall Insulation cost in Andover?
Our cavity wall insulation typically costs between £1,250 and £3,500 for a standard Andover property, depending on size, wall area, access and the number of injection points required.
As well as cutting heating bills, filling your cavities can lift your EPC rating by 1–2 bands and add around 1–2% to your property’s value. We always provide a fixed quote after survey, with no hidden extras for standard installation items.
If you receive certain benefits or your home falls within council tax bands A–D, you may qualify for full funding through ECO4 or the Great British Insulation Scheme – and with around a third of Andover homes in the lower bands, many local households do. We’ll check your eligibility as part of the survey.

Frequently asked questions
Take a look at the Frequently Asked Questions regarding our Cavity Wall Insulation services in Andover.
How much do Andover homeowners save with cavity wall insulation?
The Energy Saving Trust puts the figure at £150–£295 a year for a typical home – roughly £4,000–£7,000 over 25 years. Much of Andover’s stock is the semis and terraces of the 1960s and 1970s overspill expansion, which sit in the middle of that range; larger detached homes save more. With up to 35% of heat lost through unfilled cavity walls, the work usually pays for itself within a few years.
Will Superbead cause damp in my walls?
Not when the survey is done properly – around 96% of UK installations report zero moisture problems. The failures almost always trace back to skipped assessments or existing defects like cracked render being missed. Given the town’s exposed downland setting, we borescope every wall before filling it and won’t inject a cavity that isn’t sound.
Is my Andover home suitable for cavity wall insulation?
Most Andover homes built between 1920 and the late 1980s have standard brick cavity walls and are well suited to Superbead – particularly the 1960s and 1970s overspill estates around Floral Way, Cricketers Way and River Way. Newer estates such as Augusta Park and Picket Twenty may already be insulated, which we can confirm in minutes. The older heart of the town, though – the Georgian and Victorian properties around Church Close, Marlborough Street and Weyhill Road – was generally built with solid walls, where cavity insulation doesn’t apply; if that’s your home, we’ll say so at survey and point you towards the right solution.
What guarantee do you provide on cavity wall insulation?
All our cavity wall insulation work includes a 10-year IAA (Insulation Assurance Authority) backed guarantee covering materials and workmanship. This means you are protected even in the unlikely event that the installer is no longer trading.
How quickly can you install cavity wall insulation in Andover?
Usually within a morning: a typical Andover install takes 2–4 hours, working entirely from outside, with every drill hole sealed and made good before we leave. We confirm timings at survey – and since no interior access is needed, a Floral Way or River Way home can be insulated without disturbing anything indoors.
