Surface Doctor has provided commercial sealant services across London for over 30 years. Our clients include hotel groups, NHS facilities, restaurant chains, construction contractors, property management companies and retail developers. We cover every London borough and operate across the South East — with CHAS accreditation, fixed pricing and a 12-month guarantee on every contract.
Commercial sealant work requires a different level of planning, compliance and material knowledge than domestic jobs. Expansion joints in a hospital corridor, fire compartmentation sealing in a high-rise, food-safe silicone in a commercial kitchen, and structural glazing on a retail shopfront all need different materials, different application techniques and different documentation. Surface Doctor's team has delivered all of these and more across London for three decades.
For procurement managers and facilities teams, our CHAS accreditation provides the contractor compliance evidence you need. We carry full liability insurance, document all fire-rated work for compliance, and can work within planned maintenance programmes or respond at short notice to urgent commercial callouts across London.
Hotels require ongoing bathroom maintenance to maintain guest standards and prevent water damage. A failed shower reseal leads to mould, complaints and costly structural repairs. Surface Doctor provides hotel sealant services across London — bathroom resealing, wet room maintenance, spa and pool area sealing — on a planned or reactive basis.
Hotel sealant work we carry out:
We work around hotel operations — evenings, early mornings and planned shutdowns. CHAS accreditation satisfies most hotel group contractor requirements. Call 0345 017 0787 for a commercial quote.
Healthcare premises demand sealants that meet infection control standards. Failed or mouldy sealant in a clinical environment is a hygiene risk and a CQC compliance concern. Surface Doctor provides healthcare sealant services across London NHS trusts, GP surgeries, dental practices, care homes and private hospitals.
Healthcare sealant work we carry out:
Our CHAS accreditation meets NHS contractor compliance requirements. We can work under NHS procurement frameworks and provide full documentation. Call 0345 017 0787 for healthcare enquiries.
Commercial kitchen and restaurant environments require sealants that withstand heat, grease, moisture and frequent chemical cleaning. Failed sealant in a commercial kitchen is both a hygiene risk and a food safety compliance issue. Surface Doctor provides restaurant sealant services across London for independent restaurants, chains and contract caterers.
Restaurant sealant work we carry out:
We use only food-safe, NSF-compliant sealants in food preparation areas. We can work overnight or during kitchen shutdowns to avoid disruption. Call 0345 017 0787.
Construction projects in London require sealant contractors who can deliver to specification, on programme, with the necessary accreditations. Surface Doctor works with main contractors, subcontractors and developers across London on new build, refurbishment and fit-out projects of all scales.

CHAS accredited and fully insured. We can be named as a domestic subcontractor on your project. Call 0345 017 0787 to discuss programme requirements.
Retail fit-outs in London demand a clean, premium sealant finish that matches the brand environment. Visible joints in a high-end retail unit, food court or shopping centre need to be precisely colour-matched and neatly tooled. Surface Doctor provides shop fitting sealant services across London for retailers, fit-out contractors and shopping centre operators.
Shop fitting sealant work we carry out:
We work to retail programme timescales — overnight and weekend working available. Call 0345 017 0787 for shop fitting enquiries in London.

All fire-rated sealant work is carried out with certified materials and documented for building control and insurance compliance. Call 0345 017 0787.
