Who will be running my project?

Lewis Gormley personally surveys, prices and runs every Greenbank project. You deal with the same person from first visit through to final sign-off, not a rotating cast of site managers.

What happens if something is not right after completion?

Snagging is completed before we invoice, and our workmanship is something we stand behind — if something we built is not right, Lewis comes back and puts it right.

How do payments work?

Payments are staged against agreed milestones set out in your quotation, so you always know what has been completed before each payment falls due.

What are your opening hours?

Monday to Friday, 8:00am to 6:00pm. Saturday and Sunday closed. Enquiries submitted at the weekend are answered on the next working day.

How much does a home extension cost in Stockport?

As a guide, a single-storey rear extension typically ranges from £2,200–£3,000 per square metre for a quality finish, and double-storey from £1,800–£2,400 per square metre. Glazing, kitchens and groundworks complexity move the figure. We always issue a fixed-price quote — never a vague allowance — once we've surveyed the site.

How long does an extension take to build?

Most single-storey extensions complete in 10–14 weeks on site. Double-storey builds typically run 14–20 weeks. Planning and design usually take 8–12 weeks beforehand. We give you a written programme with key dates before work starts.

Do I need planning permission?

Many rear extensions fall under Permitted Development, but limits vary by property type, conservation area and previous extensions. We assess this for free at survey stage and submit either a Lawful Development Certificate or full planning application as required.

Will I need to move out during the build?

For rear extensions, almost never — we protect the existing house and seal off works zones. For double-storey or major structural alterations affecting the kitchen or only bathroom, a short decant is sometimes sensible. We'll tell you honestly at quote stage.

How much does a loft conversion cost in Stockport?

As a guide, our loft conversions start from around £50,000 and rise depending on type, size, en-suite specification and finishes — dormer, hip-to-gable, L-shaped and mansard conversions sit further up the range. We issue a detailed fixed-price quote after a proper site survey.

How long does a loft conversion take?

Velux conversions complete in 4–6 weeks. Dormer conversions in 8–10 weeks. Hip-to-gable in 10–12 weeks. Mansard conversions in 12–14 weeks. Planning and design usually adds 6–10 weeks beforehand.

Do I need planning permission?

Most loft conversions fall under Permitted Development if within volume limits and not in a conservation area. We confirm this for free at survey and handle the Lawful Development Certificate or full application as required.

Will I have to move out?

No. Almost all of our loft conversions are completed with the family still living downstairs. We seal off the stair opening, use external scaffold access for materials and minimise dust transfer.

How much does a garage conversion cost in Stockport?

A standard single garage conversion typically costs £15,000–£25,000 fully finished. Double garages run £25,000–£40,000. Final cost depends on whether plumbing is required (en-suite or utility) and the level of finish.

How long does a garage conversion take?

Single garage conversions typically complete in 4–6 weeks on site. Double garages 6–8 weeks. Design and Building Control approval beforehand usually adds 3–4 weeks.

Do I need planning permission?

Garage conversions are usually Permitted Development as long as the external appearance change is modest. Conservation areas and houses with existing planning conditions on the garage may require permission. We check this for free at survey.

Do I need Building Regulations approval?

Yes — always. Converting a non-habitable space (garage) to habitable use requires a full Building Regs application. We handle this end-to-end and provide the Completion Certificate on handover.

How much does a new roof cost in Stockport?

A full re-roof on a typical Stockport semi (concrete tiles, including new battens, felt and lead flashings) runs approximately £6,000–£10,000. Detached homes £9,000–£16,000. Natural slate roofs cost roughly 50–100% more. Repairs from £180.

How long does a re-roof take?

A typical semi re-roof takes 4–7 days weather-permitting. Detached properties 7–12 days. Flat roofs 2–5 days depending on size. We work to a written programme and don't strip more than we can cover that day.

How long does a new roof last?

Concrete tiles 25–35 years, clay tiles 50+ years, natural slate 80–100+ years, EPDM and single-ply flat roofs 30+ years, GRP fibreglass 25+ years. Underlay and battens typically last 30–50 years and are usually replaced at the same time.

Do you handle emergency roof repairs?

Yes — we can typically attend within 24–48 hours for active leaks and storm damage. If we can't get there immediately we'll talk you through a temporary covering to limit further damage.

How much does it cost to remove a load-bearing wall?

A typical single steel beam installation between two rooms costs £2,500–£5,500 including engineer's calcs, Building Control fees, steel supply, padstones and making good. Larger openings, multi-storey support and complex temporary works push costs higher.

How long does the work take?

A standard wall removal with single steel beam typically takes 5–10 days from prop-up to making-good. Chimney breast removals 5–7 days per breast. Larger structural openings 2–3 weeks. Underpinning 4–8 weeks depending on number of bays.

Do I need Building Regulations approval?

Yes — for any load-bearing alteration, chimney breast removal or structural opening. We submit the application, supply engineer's calcs, and arrange all required inspections. The Completion Certificate is issued on sign-off.

Will the work crack the rooms above?

Properly executed, no. We use correctly sized temporary props, install the steel before any final break-out, and use slow-set non-shrink grout to ensure full bearing. Hairline cracks in adjacent decoration can occur from vibration but are typically cosmetic.

How much does a new kitchen cost in Stockport?

Mid-range fitted kitchens (units, worktops, appliances and full installation) typically run £15,000–£30,000. Higher-end and bespoke kitchens £30,000–£70,000+. Add £5,000–£15,000 if structural alterations (wall removals) are required.

How long does a kitchen installation take?

A straightforward kitchen replacement (no structural work) typically takes 2–3 weeks on site. Kitchens involving wall removals or extensions run 4–8 weeks. We provide a written programme before work starts.

Will I have a working kitchen during installation?

There's typically a 5–10 day window with no kitchen sink or appliances. We can set up a temporary kitchen point in another room (utility, garage or dining room) with kettle, microwave and washing-up facilities.

Can you supply the kitchen as well as install?

Yes — we work with leading UK and European manufacturers and have access to trade-only ranges that aren't sold direct to the public. We can also install a kitchen you've sourced yourself.

How much does a new bathroom cost in Stockport?

Mid-range bathroom installations typically run £8,000–£15,000 fully fitted. Higher-end and luxury en-suites £15,000–£30,000+. Wet rooms add £2,000–£4,000 for proper tanking and floor formation. We always issue fixed-price quotes.

How long does a bathroom installation take?

A standard bathroom typically completes in 2–3 weeks on site. Wet rooms 3–4 weeks (tanking requires curing time). En-suite additions in loft conversions are scheduled into the wider conversion programme.

Can you supply the bathroom as well as install?

Yes — we supply any major brand from Villeroy & Boch, Duravit, Roca, Hansgrohe, Crosswater and many others. We can also install items you've sourced yourself, though we'd advise on quality before purchase.

Do you install wet rooms?

Yes — we're wet room specialists. Comprehensive tanking, formed-floor gradients to drainage, correct deflection assessment on timber floors, and concealed drainage solutions.

How much does a full renovation cost in Stockport?

As a guide, our full house renovations start from around £150,000 and move up from there depending on size, specification, structural complexity and finishes. A detailed fixed-price quote follows a full site survey and design development.

How long does a full renovation take?

Most whole-home renovations run 16–28 weeks on site, plus 4–8 weeks pre-construction. Larger or more complex properties (period restoration, structural rebuilds) can run 6–12 months.

Will I need to move out?

For full renovations, almost always yes — typically for the duration of works. Living in a property being completely refurbished is genuinely miserable, slows the trades down significantly, and adds weeks to the programme. We'll be honest at quote stage.

Do you handle planning, Building Control and party wall?

Yes — fully. Architectural drawings, structural calcs, planning applications, party-wall notices, Building Control submissions and inspections, electrical certification, gas safety. End-to-end.

Do you take on small building jobs?

Yes — we regularly take on jobs from £1,500 upwards. Smaller works are often where craftsmanship matters most, and we approach them with the same engineering standards as our larger projects.

How much does a typical brick garden wall cost?

A standard 1.8m brick garden wall (engineered foundations, single-skin with piers, capped) typically costs £350–£550 per linear metre. Heavier walls, double-skin construction and specialist materials cost more. Free survey and fixed quote provided.

Most general building jobs complete in 1–4 weeks on site. Garden walls 1–2 weeks, driveways 1–3 weeks, chimney repairs 2–7 days, porches 3–5 weeks.
