Spray Foam Removal Costs in Hampshire in 2026
Prices across Hampshire in 2026 sit within the following ranges depending on property type.
| Property Type | Typical Cost Range |
|---|---|
| Terraced house | £2,800 to £4,500 |
| Semi-detached house | £3,300 to £5,500 |
| Detached house | £3,800 to £7,500+ |
| Bungalow | £3,500 to £6,000 |
| Cottage or rural property | £3,500 to £7,000+ |
Closed-cell foam adds approximately £500 to the base cost due to the extra time and equipment required to remove it. Open-cell foam is softer and generally quicker to clear.
These figures cover removal, safe disposal, and a post-removal report for your surveyor or mortgage lender. They do not include timber repairs if damage is found underneath the foam.
What Affects the Cost in Your Hampshire Property
Foam type Open-cell foam costs from £50 per square metre to remove. Closed-cell foam costs from £70 to £75 per square metre. Most standard Hampshire lofts cover between 50 and 120 square metres.
Loft size and roof structure A compact terrace in Fratton or Shirley with a straightforward pitched roof costs considerably less than a large detached property in Winchester or Chandler’s Ford with a complex roof structure. More square metres and more awkward access both add time and cost.
Timber condition Around 40% of spray foam removals in the UK uncover some level of hidden timber damage. Spray foam traps moisture against roof timbers over time, which can cause rot and decay that is invisible until the foam is removed. If timber repairs are needed, these are quoted separately and agreed with you before any additional work begins.
Documentation requirements A post-removal report is essential if you need to satisfy a mortgage lender or surveyor. Reputable Hampshire specialists include this as standard. A report that does not meet lender requirements is worth nothing, so using an accredited company matters.
According to RICS in their official spray foam consumer guide, removal must be carried out properly and documented correctly before a surveyor can give a lender the assurance needed to proceed. Partial removal or unverified clearance will not satisfy most lender requirements.
Town by Town Cost Guide Hampshire 2026
Southampton
Southampton has a high concentration of Victorian and post-war terraced housing across Bitterne, Shirley, Portswood, and Thornhill. Most standard Southampton terraces fall in the £2,800 to £4,200 range. Larger semis in areas like Bassett or Chandler’s Ford borders sit between £3,500 and £5,500.
Portsmouth
Portsmouth’s dense terrace stock across Fratton, North End, Copnor, and Southsea tends to produce some of the more straightforward removal jobs in Hampshire. Compact loft spaces mean most Portsmouth terraces come in between £2,800 and £4,000. Properties in Cosham or Paulsgrove with larger roofs typically range from £3,500 to £5,000.
Basingstoke
Basingstoke has a significant number of 1960s and 1970s estates across RG21, RG22, and RG24 where spray foam installation was widespread during government energy schemes. Semi-detached properties here typically cost between £3,300 and £5,000 to clear. Larger detached homes in areas like Chineham or Oakridge can reach £5,500 to £7,000.
Winchester
Winchester properties tend to be larger and often have more complex roof structures, particularly in the SO22 and SO23 areas. Georgian and Victorian properties in the city centre and surrounding villages can present access challenges that add to cost. Expect £3,800 to £7,000 for most Winchester properties, with rural cottages potentially higher.
Fareham and Gosport
Post-war council-built housing across Fareham and Gosport tends to have standard pitched roofs that are straightforward to clear. Most properties in the PO13, PO14, PO15, and PO16 areas come in between £2,800 and £4,500.
Havant and Waterlooville
The PO7, PO8, and PO9 postcode areas include a mix of post-war terraces and 1960s semis. Removal costs here typically fall between £2,800 and £4,800 depending on property size and foam type.
Aldershot and Farnborough
Housing in the GU11, GU12, GU14, and GU51 areas covers a wide range from 1930s semis to 1980s estates. Most standard properties here fall between £3,000 and £5,000. Army and MOD housing stock in Aldershot occasionally presents access complexities that push costs higher.
Andover and Fleet
Andover’s post-war estates across SP10 and SP11 tend to be larger family homes. Costs here typically range from £3,500 to £6,000. Fleet properties in GU52 and GU13 vary widely depending on property age and size, with most falling between £3,000 and £5,500.
What Happens If Timber Damage Is Found
Timber repair costs vary depending on the extent of the damage. Minor treatment for early-stage moisture damage typically adds £300 to £800 to the overall cost. More significant rot affecting multiple roof timbers can add £1,500 to £3,500 or more. Full rafter replacement on a badly damaged roof is uncommon but can add considerably more.
The important point is that any damage found during removal is discussed with you before additional work is agreed. You will never face unexpected costs without your approval.
Leaving spray foam in place does not freeze the damage. Moisture continues to work on the timber underneath. A repair that costs £400 today may cost four times that in two years.
Is Spray Foam Removal Worth the Cost in Hampshire
For the majority of Hampshire homeowners, yes.
A stalled sale or refused mortgage costs real money every month it continues. Solicitor fees, estate agent time, mortgage payments on a property you are trying to leave, and the risk of losing a buyer who moves on, all add up quickly. Most Hampshire homeowners who have been through the process report that the removal cost was significantly less than the total cost of delay.
There is also the property value question. Spray foam properties in Hampshire attract lower offers, a smaller pool of buyers, and harder negotiations. Removing it restores your property to full mortgage-ready status and removes the discount buyers apply when they know foam is present.
What You Get for Your Money
A professional spray foam removal from an accredited Hampshire specialist includes the following as standard.
Full removal of all spray foam using specialist equipment. Safe disposal with a Waste Transfer Note. Complete timber inspection once the foam is cleared. A post-removal report accepted by mortgage lenders and surveyors. A 10-Year Insurance-Backed Guarantee where applicable.
This is what distinguishes accredited removal from cheaper alternatives. A report that lenders do not recognise is worthless, no matter how low the price was.
