No. 11786422 Service Overview ## Loft Conversions —The Brief, In Plain English. ### What It Is A loft conversion turns the dead space above your ceiling into a fully insulated, building-control-signed-off floor of your home. We handle everything: structural calcs, steel beams, dormer carcassing, staircase, insulation, plumbing first-fix, plastering, second-fix joinery and decoration. One crew, one accountable lead, one fixed price. ### Who It's For Homeowners in Liverpool, Ormskirk, Southport, Formby and and surrounding areas who need a third bedroom, a master suite, a home office or a teenager den — and would rather invest in their existing house than pay stamp duty and estate agent fees on a bigger one. ### When You Need It Get the survey booked the moment the family outgrows the floorplan. Most loft conversions add a usable room inside 8–12 weeks on site, and the kit-off date is shorter than a house move. School catchments, working from home and ageing parents are the three reasons we hear most often — all of them benefit from acting sooner rather than later. ### Why It Matters A loft conversion done properly typically returns 15–20% on the property's market value while costing a fraction of moving. Done badly it's a damp, cold, head-bashing crawlspace that scares off every surveyor. The structural carpentry is what makes the difference — and that is exactly what a joiner-led firm gets right first time. What Happens If You Wait ## The Cost OfDoing Nothing. Most loft horror stories we get called to rescue have the same root cause: a generalist builder who underspecced the steels, skimped on insulation depth, or treated the staircase as an afterthought. By the time it gets to building control sign-off, the bill to put it right is bigger than the original quote ever was. ### Risks Of Ignoring It - →Undersized steels or rafter trimmers — visible deflection, cracked ceilings below, structural rejection at sign-off. - →Cold roof build-ups with no ventilation gap — interstitial condensation, black mould inside the insulation within 18 months. - →Staircases that fail Part K headroom — building control will not sign off and the room becomes legally unusable. - →Dormer flashings sealed with mastic instead of lead — water ingress at the first proper Northwest winter. - →No fire-door upgrades to the existing landing — invalidates buildings insurance and the conveyancer will flag it on sale. ### Common Mistakes Customers Make - ×Hiring on price alone — the cheapest quote almost always has structural steels missing. - ×Using a designer who never visits site — drawings that look great on PDF and don't build. - ×Skipping the party-wall agreement on terraces and semis — neighbours can stop the job mid-build. - ×Buying the Velux windows before the survey — wrong size, wrong rating, wrong opening direction. - ×Letting a plasterer board out before insulation is signed off — entire ceiling comes back down.

Working across Huyton · Liverpool · Prescot · Whiston · Knowsley · Kirkby Full Service Area Map ### Dormer Loft Conversions The workhorse of UK loft conversions. A flat-roof or pitched dormer pushes the rear roof slope outward to create full standing headroom and a flat wall for windows, wardrobes and en-suite fittings. We handle structural carcassing in C24 graded timber, EPDM or GRP roof covering as preferred, lead flashings to all abutments, and a fully insulated build-up that hits current Part L u-values. Typical dormer conversion adds one double bedroom plus en-suite to a standard 1930s semi. ### Hip-To-Gable Conversions For end-terrace and semi-detached properties with a hipped side roof. We rebuild the hip as a vertical gable wall in matching brick or render, opening up the full ridge length for usable floor area. Almost always paired with a rear dormer to maximise the gain. Structural steels typically run from the new gable to the existing party wall — designed by a structural engineer, signed off by building control. ### Velux / Rooflight Conversions The lightest-touch option — no external alteration to the roofline, no planning permission in most cases. Suits steeper-pitched roofs where headroom is already adequate. Floor strengthened with trimmer joists, Velux Conservation or GGL units fitted flush, full insulation upgrade, new staircase, building control sign-off. Quickest on site and cheapest, but limited to roofs that already have the geometry. ### L-Shape & Mansard Conversions L-shape conversions exploit the rear outrigger on Victorian and Edwardian terraces — typically two dormers connecting at right angles to create a master suite plus separate en-suite. Mansards rebuild the entire rear roof slope to near-vertical, maximising floor area but usually requiring planning permission. Both demand careful structural design and weather-detail experience — exactly the kind of work a joiner-led firm gets right. ### Staircases, Fire Safety & Building Regs The new staircase is the single most-failed element at building control sign-off. We design every stair to Part K — 220mm max rise, 2m clear headroom, 800mm minimum width — and integrate it into the existing landing without sacrificing the bedroom you already have. Fire-door upgrades, mains-wired interlinked smoke alarms and 30-minute fire-rated ceilings below are included as standard on every conversion we deliver.

Ask Yours ### How much does a loft conversion cost in Liverpool? +A standard rear-dormer conversion on a 1930s semi typically runs £45,000–£65,000 inclusive of structural works, en-suite, building control and decoration. Hip-to-gables run £55,000–£75,000. Velux-only conversions start around £28,000. Every job is priced in writing after a free site survey — we don't quote blind over the phone. ### How long does a loft conversion take? +On-site time for a standard dormer conversion is typically 8–10 weeks from roof-off to handover. L-shapes and hip-to-gables run 10–14 weeks. We give you a programmed start date, weathertight date and completion date in writing with the quote — and we hit them. ### Do I need planning permission for a loft conversion? +Most rear dormer and Velux conversions fall under permitted development (PD) and don't need planning. Front-facing dormers, mansards and conservation-area properties usually do. We check the planning portal as part of every survey and tell you straight. ### Will building control sign off my loft conversion? +Yes — and we manage the application, inspections and completion certificate end-to-end. Notifiable works are submitted to the appropriate local authority or private building control firm depending on the address. The certificate is in your hand on the day we leave site. ### Can I stay in the house during the build? +Yes. Most of the disruptive work is overhead and self-contained. The roof comes off in a single planned weather window, the dormer is weathertight inside days, and the existing house stays sealed throughout. We dust-sheet the existing landing and stair to the loft access from day one. ### What guarantee do you offer on loft conversions? +Ryan will return to fix any workmanship issue within 5 years of completion. Roof coverings carry the manufacturer's warranty (typically 15–25 years depending on product). Building control completion certificate is your statutory sign-off. RG Loft Conversions & Extensions Ltd is fully insured — Company No. 11786422. ### Will a loft conversion add value to my house? +A properly executed loft conversion that adds a legitimate bedroom plus en-suite typically returns 15–20% on the property's market value. The key word is 'legitimate' — bedroom must meet building regs for headroom, fire safety and means of escape, or surveyors will discount it. ### Do you cover my area? +We cover Liverpool, Ormskirk, Southport, Formby, Skelmersdale and surrounding Northwest England on a sensible travel radius from our Huyton base. If you're outside that list, call us anyway — we'll tell you straight. Next Step ## Ready To Talk About Your Loft Conversion?
