What Prokil Ltd does

Prokil Limited is a privately held, family-run damp proofing, timber preservation, and basement waterproofing company headquartered in Bournemouth, Dorset. Founded in the 1960s (with company registration 4348686), the firm has operated for over 50 years and claims to have served more than 37,000 clients across the South of England and Wales. Its primary customers are residential property owners facing rising damp, penetrating damp, condensation, mould, wet rot, dry rot, and woodworm, alongside commercial clients including housing associations, local authorities, NHS trusts, schools, universities, heritage buildings, hotels, and private landlords. Named engagements include waterproofing work for Dorset HealthCare University NHS Foundation Trust's Codestone House facility, rising damp treatment for Francesco Group Salon & Academy in Poole, and dry rot remediation at a Bournemouth church.

The company's core service portfolio spans damp services (DPC injection to BS 6576, damp-proof plastering, ventilation systems including passive air vents and positive pressure ventilation), timber services (treatment, preservation, repair and replacement), structural repairs (cavity wall tie replacement, crack stitching, asbestos surveys), water damage restoration, basement tanking and waterproofing (including Newton cavity drain membrane systems and sump pumps), and property surveys. Treatment work is backed by 20-year guarantees insured via Guarantee Protection Insurance (GPI). The technology stack is built on conventional building science: specialist moisture measurement using Protimeter equipment, chemical injection treatments, cementitious tanking renders, and certified membrane systems — with surveyor qualifications (CSRT, CSTDB, CSSW) and accreditations (PCA, TrustMark, CHAS, ISSE, Newton Specialist Basement Contractor, Sovereign approved, Pam Ties approved) forming the credibility layer.

Prokil operates a survey-led, non-commission sales model in which qualified surveyors conduct initial assessments and provide recommendations rather than using commissioned salespeople. Revenue is generated through per-project quotes for treatment work plus survey fees (which may be waived depending on circumstances), with a price-match guarantee across services. Distribution combines direct service delivery from the Bournemouth HQ and branch offices (Hove, Cranleigh, Rumney) with a franchise network (Prokil Crawley, Prokil Brighton/Worthing, Prokil Cardiff/Newport) operating under the Prokil brand with their own company registrations. Customer acquisition is driven primarily by local SEO across 50+ location pages, content marketing via case studies and educational blog content, and Checkatrade review accumulation (261 reviews at 8.23/10 overall, 9.65/10 in Worthing). ProStar Energy operates as a sister company providing solar PV, battery storage, and EV charging services with cross-referrals from Prokil's property-care customer base.
