Loft Conversions - Dormer · Hip-to-Gable · Velux - Structural calcs in-house - Building Control filed by us - Fire-rated escape compliant - 1-year workmanship guarantee Service overview ## What's involved in loft conversions. Plain-English breakdown, so you know exactly what you're paying for and why it matters before we set foot on site. ### What it is Full loft conversions, dormer, hip-to-gable, mansard and Velux, including structural ridge beams, fire-rated escape routes, insulation to current Part L, electrics, plumbing for en-suites, plastering and decoration. Sign-off and certificates issued in your name. ### Who it's for Families needing a fourth or fifth bedroom, homeowners adding an en-suite master, and remote workers wanting a quiet office above the noise of the house. ### When you need it You've outgrown the house but love the postcode; you want to add value before resale; or the existing loft is wasted insulation and storage and you're ready to make it habitable. ### Why it matters Loft conversions add bedroom count and floor area without losing garden or paying stamp duty on a bigger house. Done correctly, they typically return 15–25% on the property value. The cost of doing nothing ## What goes wrong when this is ignored. Loft conversions look simple from the street and complex from the inside. Fire compartmentation, head height and structural transfer are the three things most cheap quotes get wrong. ### Risks of waiting - Inadequate fire-rated doors and protected escape routes can fail Building Control and stop a sale. - Under-sized ridge or floor beams cause sagging that only shows once plaster has cracked. - Poor insulation detailing creates cold bridges and condensation in eaves storage. - Dormer flashing done badly leaks within two winters and damages the new plaster below. ### Common mistakes - Choosing a quote that doesn't include the staircase, en-suite or full decoration. - Skipping the structural calc and trusting a builder's 'we always use a 203 UB'. - Forgetting the loft hatch needs to become a proper stair on a compliant landing. - Underestimating the disruption of opening the roof for the dormer week. Our process ## How the job actually runs. Same system every time. No improvising on your floor. 1. 01 ### Free on-site survey We measure head height, ridge position, joist span and existing services to confirm the right conversion type. 2. 02 ### Fixed written quote Itemised quote within 48 hours covering structure, dormer or rooflights, staircase, en-suite, finishes and Building Control. 3. 03 ### Design & engineering Architect drawings co-ordinated, structural calcs produced, Building Regs application filed. 4. 04 ### Build phase Typical 6–10 week programme with weather-tight roof opening sequenced for dry weeks where possible. 5. 05 ### Sign-off & handover Building Control completion certificate, EICR for new circuits, warranties and a 1-year Spectrum workmanship guarantee. What you get ## The outcomes that matter. ### Extra bedroom, no lost garden Add floor area upwards rather than out into the lawn. ### Adds resale value A compliant loft conversion typically returns 15–25% on property value in TN postcodes. ### Fully certified Building Control sign-off, fire compliance and electrical EICR all in your name at handover. ### Tidy build Dust-sheeted access route, protected staircase and daily clean-down, the house stays liveable. ### Fixed price What we quote is what you pay; variations are signed before any extra work begins. ### 2-year guarantee Workmanship guarantee on every joint, junction and finish. In depth ## Everything worth knowing before you book. The details a salesperson skips. Skim it, or read every word, both are useful. Questions on this? Talk to a Spectrum tradesman direct. [07480 485988](tel:+447480485988) ### Dormer loft conversions The most common option for Victorian and 1930s Tunbridge Wells stock, a rear dormer adds full standing head height and the floor area for a double bedroom plus en-suite. We handle structural ridge beams, dormer cheeks and roof in zinc or tile, large rear glazing, full insulation to Part L, and a compliant staircase up from the existing landing. ### Hip-to-gable conversions Where the existing roof has a hipped end (common on 1930s semis and detached), we square the gable up to ridge height and add a rear dormer for maximum usable floor area, typically two bedrooms and an en-suite from a previously unusable loft. ### Velux-only conversions Where head height already exists (steeper roof pitches and Victorian terraces), Velux rooflights alone can create a beautiful bright bedroom or office without the cost or planning of a dormer. Quicker programme, lower budget, same standard of insulation and fire compliance. Frequently asked ## Straight answers, no fluff. Can't see your question? Call [07480 485988](tel:+447480485988).
