In detail

What each job covers

Extensions

Planning and design, securing foundations, brick and block construction, roofing, internal plastering, electrics, plumbing, flooring and final decorating.

When you need it. When existing rooms are too small, there's no suitable space for a growing family, or an extra bedroom or workspace is needed.

Before you get in touch. Measure available space. Check boundary lines and neighbouring properties. Have rough ideas on layout and budget.

Loft Conversions

Structural surveys, roof strengthening, stairs installation, flooring, insulation, electrical wiring, plasterboarding, and finishing to create habitable rooms.

When you need it. When attic space is wasted, extra bedroom or office needed, and building outwards is not an option.

Before you get in touch. Measure loft dimensions and headroom. Check roof condition. Consider roof windows or skylights.

Renovations

Structural assessment, rewiring, replumbing, removing or moving walls, new bathrooms and kitchens, decoration, flooring and all finishes.

When you need it. When properties are outdated, damaged from age, or need complete modernising for comfort and value.

Before you get in touch. List specific areas needing work. Take photos. Note any known issues with damp, electrics or plumbing.

Brickwork

Repointing joints, replacing damaged bricks, building new walls, chimney repairs, and brick cleaning on residential and commercial properties.

When you need it. When mortar is crumbling, bricks are loose or damaged, water is getting in, or walls need rebuilding.

Before you get in touch. Note affected areas and whether damage is structural. Check if any movement has occurred in walls.

Groundworks

Site clearing and levelling, drainage systems, foundation excavation, concrete bases, external landscaping and hard-standing installation.

When you need it. At the start of new builds, before extensions, when drainage fails, or to prepare sites for construction.

Before you get in touch. Obtain site surveys. Check underground utilities location. Know soil type and drainage requirements.

New Builds

This is where a real Google review appears. When a customer leaves you five stars, their words show here — in their name, with their rating and the date they wrote it.

A recent customer
Example

Reviews are pulled from your Google Business Profile, so this section fills itself. Nothing to write, nothing to keep up to date.

Another customer
Example

The most recent reviews show first, so the page keeps pace with the work without anyone touching it.

Good to know

Common questions

General guidance about builders in the UK, not specific to any one business.

Do I need planning permission for an extension?

Most single-storey extensions under certain sizes qualify for permitted development, but checks depend on location, boundary distance and existing building type. Planning permission is always needed for larger extensions. Local councils have specific rules.

How long does a loft conversion take?

Typical conversions take 8 to 12 weeks depending on complexity, whether the roof needs strengthening, and how much structural work is needed. Building control inspections and final sign-off add to the timeline.

What makes brickwork fail and crumble?

Mortar deteriorates from age, weather exposure, poor original mix, or water penetration. Bricks themselves can spall from frost damage or rising damp. Movement in the building can also crack and displace pointing.

What happens during groundworks for a new build?

The site is cleared and levelled. Surveys check soil type and underground services. Foundations are dug to required depth, drainage systems installed, and the base prepared for the building structure.

Can a loft conversion be done in a terraced house?

Yes, but party walls are involved, so a Party Wall Act notice must be served to neighbours. Structural limitations may apply depending on roof design and supporting walls.

What should I budget for a renovation?

Costs vary widely by scope—replacing kitchens and bathrooms, rewiring, replumbing and structural work all add up. Old properties often reveal hidden problems once work starts, so contingency funds are essential.
