What Is Stone Restoration?

Your stonework is deteriorating. We can fix it.

London's Victorian, Georgian and Edwardian buildings are built to last. Without maintenance, decades of pollution, rainfall and biological growth take their toll. Stone becomes stained, mortar joints fail and structural problems develop. The longer it's left, the more it costs to fix.

Professional stone restoration reverses that damage. At LBC Exterior Cleaning, we assess every stone before we touch it. We select the correct method for the material and its condition. Using the wrong technique causes permanent damage. Getting it right from the start is what matters.

We are one of a small number of London contractors holding Stonehealth DOFF Approved status. Recommended by the manufacturer. You get expert care, not guesswork.

DOFF Steam Cleaning

DOFF is a specialist superheated steam system by Stonehealth. It delivers steam at up to 150°C at very low pressure, cleaning without abrasion or chemical damage. As Stonehealth DOFF Approved contractors, we are certified to operate it on any stone type, including listed buildings.

About DOFF cleaning →

TORC & IBIX Cleaning

For deposits that steam cannot shift, limescale, calcium and heavy carbon, we use TORC or IBIX. TORC uses a gentle swirling mix of air, water and fine media. IBIX is a wet abrasive system for the toughest staining. Both protect fragile stone where high-pressure washing would cause damage.

TORC cleaning service →

Stone Sealing & Protection

Once restored, we apply impregnating sealers to protect your stone from future staining, weathering and biological regrowth. The right sealer lets the stone breathe while extending the life of the clean significantly.

Stone Restoration for London's Historic Properties

London's architectural heritage demands a different level of care. The wrong cleaning method causes irreversible damage to historic stone, particularly on Georgian, Victorian and Edwardian facades that have stood for over a century.

We work regularly on period properties, listed buildings and conservation area buildings. DOFF steam cleaning is widely specified for heritage work because it cleans effectively at low pressure, protecting fragile historic stonework.

Unsure whether you need listed building consent or planning permission? We advise on this during the survey stage.

FAQ

Frequently Asked Questions

Stone cleaning and sealing typically costs £10 to £25 per m2. More comprehensive facade restoration including repointing and stone repair ranges from £80 to £250 per m2 or more, depending on the stone type, extent of damage and access requirements. We provide free, no-obligation written quotes after a site survey.
The best method depends on the stone type and level of contamination. DOFF steam cleaning uses superheated water at low pressure and suits most natural stone. TORC uses a swirling mix of air, water and fine media for stubborn deposits like limescale and carbon. IBIX is a wet abrasive system for the toughest staining. We assess the stone before recommending anything. The wrong choice causes permanent damage.
Yes, when the right method is used. The DOFF steam cleaning system by Stonehealth is the only system approved by English Heritage for cleaning historic stonework. As Stonehealth DOFF Approved contractors, we are trained and certified to use it on listed and heritage buildings. We always carry out a test patch first so you can approve the result before full works begin.
Works that affect the character of a listed building may require listed building consent from your local planning authority. We work regularly on listed properties and conservation area buildings. We can advise on permissions during the survey stage.
Smaller residential projects typically take one to three days. Larger facade restorations or commercial projects may take one to two weeks or more, depending on the extent of works and access requirements. We provide a clear project timeline after the site survey.
DOFF uses superheated steam at low pressure. Gentle on delicate stone, effective at removing organic growth, paint and grime without abrasion. TORC uses a rotating vortex of air, water and fine inert media to lift stubborn deposits like limescale and heavy carbon. IBIX is a wet abrasive system for the toughest staining. All three are low-impact alternatives to high-pressure washing.
Yes. Well-maintained stonework improves kerb appeal and adds measurable value to a property.
