Terms & Conditions of Service
Last Updated: May 2026
These Terms and Conditions govern all specialist building cleaning, restoration, conservation, and stonemasonry works undertaken by Stone Revival Ltd and/or Clarke Heavey Stonemasonry Ltd. In this document, references to "the Company" refer to either or both corporate entities as identified on the project quotation, and "the Client" refers to the person, firm, or company appointing us.
SCOPE OF QUOTATIONS & VARIATIONS
1.1 Validity: All written quotations are valid for thirty (30) days from the date of issuance. After this period, the Company reserves the right to amend pricing to reflect fluctuations in material, logistics, or labour costs.
1.2 Acceptance: A contract is formed, and these terms are deemed fully accepted, upon the Client providing written confirmation (including email), signing our project acceptance form, or authorising the commencement of works on site.
1.3 Variations & Extras: Any additions, omissions, or alterations to the scope of work detailed in the original quotation must be agreed in writing. Additional works will be billed as variations at our standard commercial day/hourly rates plus material margins, unless a fixed supplemental quotation is agreed.
1.4 Latent Defect Discovery: Specialist cleaning and masonry works often expose hidden architectural realities. If unforeseen structural defects, unstable masonry, voids, structural movement, or hazardous substances (e.g. asbestos) are uncovered during the works, the Company reserves the immediate right to suspend operations. We will notify the Client, and provide an amended scope and cost breakdown before proceeding.
2. SITE ACCESS, UTILITIES & PERMISSIONS
2.1 Unobstructed Access: The Client must ensure clear, safe, and continuous physical access to the building perimeter, designated work zones, and layout areas for the full duration of the project. This includes maintaining clear thoroughfares for our commercial vehicles, equipment, and technicians.
2.2 Provision of Utilities: Unless explicitly stated otherwise in our quotation, the Client is strictly responsible for providing a continuous, reliable supply of 240V/110V mains electricity and a high-volume, mains-pressure clean water supply at no financial cost to the Company. Any failure to provide these utilities that halts operations will trigger standing time fees.
2.3 Statutory Consents & Licences: The Client holds sole legal responsibility for obtaining all necessary public and local authority approvals prior to site mobilisation. This includes, but is not limited to: Listed Building Consent, conservation area permits, scaffolding permits, pavement licences, parking suspensions, and neighbour boundary agreements (Party Wall Acts). The Company accepts zero liability for delays or fines arising from missing statutory permissions.
3. SCAFFOLDING, ACCESS EQUIPMENT & STANDING TIME
3.1 Company-Supplied Access: Where the Company quotes to provide scaffolding, powered access booms (cherry pickers), or specialist towers, this equipment is provided strictly for our own operational use, unless a shared-use agreement is explicitly drafted and insured.
3.2 Client-Supplied Access Requirements: Where the Client undertakes to supply scaffolding, independent towers, or access machinery, all such equipment must be completely erected, fully boarded, structurally tied, certified safe, and legally tagged (e.g. Scafftag system) in strict compliance with the Work at Height Regulations 2005 and health & safety legislation, prior to the scheduled arrival of our team.
IMPORTANT: CLAUSE 3.3 – NON-COMPLIANT ACCESS EQUIPMENT & STANDING TIME FEE
If any client-supplied access equipment is found to be unavailable, incomplete, untagged, structurally non-compliant, or deemed unsafe by the Company's site supervisor or safety officer upon arrival, our operatives will not step onto the equipment.
In such circumstances, the project will be placed into immediate suspension, and the Client will be billed a mandatory Standing Time Fee of £65.00 per hour per operative (or a flat operational day rate of £450.00 per operative, whichever is lesser) for all hours our crew remains idle on site. If the defect cannot be remedied within two (2) hours, the Company reserves the right to demobilise the crew from the site. The Client will bear all associated remobilisation charges.
4. NATURAL STONE CHARACTERISTICS & CLEANING OUTCOMES
4.1 Natural Product Variations: The Client explicitly acknowledges that natural stone, marble, granite, and limestone are organic, geological materials. Natural variations in colour shading, structural veining, mineral inclusions, texture, and natural porosity are inherent characteristics. While the Company will exercise expert professional skill in sourcing matching stones for indent repairs, masonry replacements, or pointing mortars, a seamless or identical match to historical, weathered, or seasoned stone cannot be guaranteed.
4.2 Cleaning Limitations: The Company utilises industry-leading systems (including DOFF steam systems, TORC abrasive cleaning, and specialised chemical poultices). However, cleaning processes are designed to strip away atmospheric pollution, biological carbon crusts, organic growths, and modern paint layers. We cannot guarantee the complete removal of deeply ingrained, historical mineral stains, metallic oxidation (rust within the stone matrix), or subterranean efflorescence that has chemically bound to the stone substrate over decades.
4.3 Test Patches: Where sample test areas are conducted prior to contract commencement, they represent a localised indication of possible results. The Company gives no absolute guarantee that the final, macro-level result across a vast, complex façade will precisely mirror the localised test patch.
5. LIABILITY, PRE-EXISTING CONDITIONS & PROPERTY PROTECTION
5.1 Pre-Existing Structural Degradation: The pressure, heat, and chemical reactions required to effectively clean architectural stone can exacerbate hidden flaws. The Company accepts no liability whatsoever for the failure, fracturing, or dislodgement of pre-existing degraded mortar joints, structurally blown or spalling stone, loose decorative features, or improperly secured architectural elements that fail under standard operational parameters.
5.2 Water Ingress: While the Company takes extensive, professional precautions to shield window openings, vents, doors, and expansion joints using protective sheeting and tape, the Client acknowledges that high-pressure steam and water cleaning carries an inherent risk of moisture movement. The Company shall not be held liable for internal water ingress, dampness, or cosmetic internal damage caused by underlying structural defects, failing window seals, degraded pointing, or porous brick/stone envelopes.
5.3 Protection of Surrounding Areas: The Company will take reasonable precautions to protect adjacent surfaces, glass, vehicles, and landscaping. The Client must move any highly sensitive or transportable assets (such as vehicles, patio furniture, and potted plants) clear of the operational splash zone prior to work commencing.
5.4 Public Liability & Notification Window: The Company maintains comprehensive Public Liability Insurance. Any claim for physical property damage directly caused by our technicians' negligence must be formally documented and reported to our head office in writing, accompanied by photographic evidence, within 48 hours of project completion. The Company will not recognise any liability claims raised after this window or after subsequent trades have occupied the work zone.
6. PROJECT CANCELLATIONS & POSTPONEMENTS
6.1 Notice Requirements: If the Client needs to reschedule, postpone, or cancel a confirmed project booking, they must deliver formal written notice to the Company no less than 7 business days prior to the agreed mobilisation date.
6.2 Short-Notice Cancellation Charges: Cancellations or major postponements made within 7 business days of the project date will incur a cancellation charge equivalent to 25% of the total labour value of the quoted project, alongside 100% of the cost of any custom-ordered, non-returnable architectural stone elements.
7. GOVERNING LAW & JURISDICTION
These Terms and Conditions, and all contractual relations between the parties, are governed exclusively by and construed in accordance with the laws of England and Wales. Both parties irrevocably agree that the courts of England and Wales shall hold exclusive jurisdiction to settle any disputes, claims, or legal proceedings arising out of or in connection with these terms.
