Maintain patio & trees.

A combined maintenance approach ensures that your outdoor living space remains safe, level, and clean. By addressing tree health and patio repairs simultaneously, you prevent long-term damage that could lead to a full and costly patio replacement.

What Does the Work Involve?

• Structural Assessment: Inspecting slabs for movement, subsidence, or "rocking" caused by tree root activity beneath the surface.
• Tree Surgery: Pruning overhanging limbs, crown lifting to allow more light, and removing deadwood to prevent storm damage to the patio.
• Surface Cleaning: Deep cleaning the stone or concrete using professional-grade pressure washers or chemical treatments to remove lichen and algae.
• Repointing and Re-bedding: Removing failed mortar joints and replacing them with modern resin or sand-cement mixes, and re-setting any loose slabs.
• Root Management: Carefully pruning surface roots where possible or installing root barriers to protect the patio’s sub-base.
• Waste Disposal: Chipping all timber arisings and removing garden waste, leaving the site tidy and ready for use.

Typical Costs

Prices are influenced primarily by access and the height of the trees involved. If a cherry picker or specialist scaffolding is required to reach branches safely over a conservatory or glass roof, costs will increase significantly.

How Long Does It Take?

• Minor Maintenance: 3–5 hours for basic pressure washing and light pruning of small fruit trees or shrubs.
• Standard Repair: 1 full day for crown lifting one large tree and repointing a medium-sized (20m²) patio.
• Major Restoration: 2–3 days for significant tree surgery, root grinding, and lifting/re-bedding multiple damaged slabs.

DIY or Professional?

Homeowners can easily handle basic leaf clearance and light pruning with hand shears. However, any work involving chainsaws, heights, or structural slab movement should be left to professionals.

Tree surgery is high-risk work; professional arborists carry specific insurance and have the training to prevent heavy branches from falling and shattering your paving.

For patio repairs, a professional ensures the sub-base is correctly compacted. If you have a Tree Preservation Order (TPO) on your property, a professional must handle the paperwork and execution to avoid heavy fines.

Choosing the Right Tradesperson

• Check Credentials: Look for NPTC or LANTRA qualifications for tree work and Checkatrade or TrustMark for paving.
• Insurance: Ensure they have Public Liability insurance (minimum £5 million is standard for tree work).
• Waste License: Confirm they are a registered upper-tier waste carrier to ensure your garden debris isn't fly-tipped.
• Ask: "How will you protect my existing paving from heavy machinery or falling branches?"
• Ask: "Can you identify if my tree is subject to a TPO or in a Conservation Area?"
• Ask: "What type of jointing compound do you recommend for my specific stone type?"

UK Regulations

• Tree Preservation Orders (TPO): It is a criminal offence to cut or prune a tree protected by a TPO without local council consent.
• Conservation Areas: You must give the Local Planning Authority six weeks' notice before carrying out work on trees in these zones.
• British Standard BS 3998: This is the UK standard for tree work; all professional arborists should work to these guidelines.
• Part P & Underground Services: While not Part P specific, installers must check for shallow-buried electrical cables or gas lines before digging near roots.

Common Problems

• Root Heave: Large roots lifting slabs. This often requires a professional to assess if the root can be safely pruned without killing the tree.
• Algae and Slip Hazards: North-facing patios under dense tree canopies stay damp, creating dangerous, slippery surfaces that require annual treatment.
• Incompatible Mortar: Using cheap sand and cement on natural stone can cause "picture framing" stains; always use the correct resin for the stone.
• Bird Droppings and Sap: Certain species like Lime trees drop "honeydew" which encourages black sooty mould on patios, requiring specialist biocide cleaners.
