Everything you need to know about our 5-stage thermal restoration process, fixed pricing structure, guarantees, and environmental safety.
Most driveways cost between £480 and £1,050, depending on size, surface material, and how deep the lichen root hyphae have anchored into the stone pores.
A typical two-car block-paving driveway takes 3 visits across 5 days and falls right in the middle of that range. The final figure is fixed in writing before any work starts.
A £150 jet washer is selling a 1-hour, high-pressure cold-water blast. While cheap upfront, raw pressure strips historic stone faces, blasts soft lime mortar out of jointing, and leaves lichen roots alive 1.5mm deep inside stone pores—meaning spots return within months and your paving suffers cumulative structural damage.
Our quotes reflect a 3-visit, 5-stage thermal restoration & conservation service using 160°C superheated steam, Bilt Hamber degreasers, complete inter-stage drying, fresh kiln-dried joint re-sanding, and optional Smartseal™ barrier coats. You aren't paying for a quick wash; you are hiring a specialist to protect a multi-thousand-pound asset safely without toxic chemicals or structural risk.
It is priced per job, as a fixed lump sum—not by a vague square-metre rate.
Square-metre rates hide unexpected extras. I measure the area, assess the surface porosity, and give one firm price for the entire 3-visit process. If it says £650 on your written quote, £650 is exactly what you pay on completion.
Overall surface area is the main driver, but surface type and infestation age also matter.
Older, deep-rooted crustose lichen on soft Indian Sandstone or porous concrete block paving takes more thermal energy and time than light growth on newer stone. I will show you the exact penetration depth during your free assessment.
No—the site assessment and written quote are 100% free.
You receive a firm, no-obligation figure before making any decisions, with zero sales pressure. You can review the quote in your own time.
There is a minimum job charge of £250, which covers small pathways, doorsteps, or isolated garden features across our multi-visit schedule.
For anything smaller than that, it is rarely worth paying a professional contractor, and I will tell you so honestly rather than quote an unrealistic price.
Yes—every price I quote is fully inclusive.
There are no surprise percentages or hidden fees added at the end; the figure on your written quote is the exact figure on your final invoice.
The price covers our full 5-stage treatment protocol delivered across 3 site visits: pre-soak degreasing, calibrated rotary clean, 100°C steam thermal shock, kiln-dried joint re-sanding, and complete site cleanup.
You are not asked to do any preparation beforehand—we handle the job from start to finish.
Lichen eradication, black-spot thermal shock, deep cleaning, and fresh kiln-sand joint replenishment are included in all standard quotes.
Applying 2 coats of heavy-duty Smartseal™ acrylic sealer is included in full restoration packages or priced separately as an option. I will only suggest sealing if your paving will genuinely benefit from long-term oil and weed defense.
No—black spot and organic staining are treated as part of the same core service.
Black spots (Verrucaria nigrescens) are part of the crustose lichen family. Charging extra for them as a "separate service" would be unfair, so everything is handled in one complete package.
Yes—our process relies on liquid thermodynamics (100°C water), not toxic bleach or caustic acids.
There is zero chemical runoff to scorch manicured lawn borders, harm soil biology, or endanger domestic pets. Furthermore, controlled 100°C liquid heat operates far below concrete thermal stress thresholds (220°C+), keeping your stone binder 100% safe.
No—you pay zero deposit.
Nothing is due until all 3 site visits are complete and you have personally inspected the finished paving. The only document signed beforehand is your written quote, ensuring you know the exact cost upfront.
Payment is made by bank transfer or debit/credit card once Visit 3 is completed and you are completely satisfied with the result.
A formal itemized invoice is issued for every single job, whether it is a small doorstep or a full estate courtyard.
Yes—Venture Exteriors holds full Public Liability Insurance up to £1,000,000.
You are welcome to view our insurance certificate during your free site assessment; asking for proof of insurance is a fair question and I encourage every homeowner to check.
Every full restoration treatment includes a written 12-month re-treatment guarantee.
While airborne spores exist naturally in the UK environment, if any lichen recolonizes within your 12-month guarantee window, I will return and re-treat the affected area at zero additional cost.
Our process takes place across 3 separate visits over a 5-day period to allow complete inter-stage drying:
We are booking site assessments now for active restoration treatment slots.
Spring and summer are our busiest seasons for paving restoration across North Essex, so requesting your site assessment early secures your preferred calendar window.
No—as long as we have outdoor access and an active outdoor tap, you do not need to stay at home.
We confirm gate access during the initial assessment and send you a text update upon arrival and completion of each visit stage.
We cover all of North Essex and surrounding estates—including Great Horkesley, Boxted, West Bergholt, Nayland, Dedham, and Colchester—with zero travel charges.
For larger estates located further afield, any minor travel considerations are clearly stated on your quote before you agree to anything.
High-pressure jet washing uses raw kinetic water force to shear off only the upper surface crust of the lichen. However, fungal root hyphae remain alive 1.5mm deep inside stone micro-capillaries, causing spots to return within months.
Worse, jet pressure erodes concrete face aggregate and blasts out kiln joint sand. Our hydrated 100°C thermal shock method eradicates sub-surface root hyphae through heat without pitting or damaging stone.
DIY chemical treatments (like household bleach or cheap patio cleaners) rely on heavy sodium hypochlorite that temporarily bleaches organic pigments white rather than destroying subterranean roots. As moisture evaporates, salt crystals expand inside stone pores, causing internal capillary cracking.
That said, if your paving has only a tiny, isolated 6-inch cluster, I will tell you honestly during your assessment how to treat it yourself rather than paying for a professional visit!
