Cavity Wall Insulation has been surveying and installing in Romsey for years — cavity-wall fill, loft top-ups, internal and external wall systems, and underfloor work. Romsey sits on a band of older Victorian and Edwardian housing closer to the centre, with newer cavity-wall developments pushing outwards.
Romsey sits on a band of older Victorian and Edwardian housing closer to the centre, with newer cavity-wall developments pushing outwards. We approach the two completely differently — breathable internal systems and lime-compatible details for the older fabric, standard CIGA-guaranteed bead for the modern stock.
Romsey sees its share of cold snaps each winter, and uninsulated rooms drop temperature rapidly overnight. Customers typically report bedrooms holding warmth two to three hours longer the first night after a cavity fill — a small thing, but a noticeable one.
Whatever your property type, we'll specify the right system. These are the services we install across Romsey and the surrounding area.
Top-up or full re-lay to current depth standards, with hatch draught-proofing.
Bonded bead or blown fibre, drilled and pumped with a written 25-year guarantee.
Render-finish system for solid-wall homes — warmth and weatherproofing in one.
Slim breathable boards for listed and conservation properties.
Mineral wool or rigid board between joists; stops cold from below.
Safe foam removal from awkward voids, surveyed and extracted to current standards.
For 1970s–1990s detached homes in Romsey, the original cavity bead has often partially slumped. A borescope inspection tells us within ten minutes whether a top-up or a full extract-and-refill is needed.
Surveys in Romsey are free, written quotes are itemised, and we don't take deposits for jobs under £3,000. Pay on completion, after you've walked the site with the install lead.
Four steps, no surprises. We follow the same process on every property in Romsey.
A local surveyor visits, inspects the loft, walls and any exposed floor voids, and asks about damp history, ventilation and any planned building work.
Itemised by measure — loft top-up, cavity fill, EWI per elevation — with materials, guarantee scope and labour broken out separately. No surprise extras.
Two or three-person team, dust sheets down, all access points (loft hatch, drilled holes) reinstated and made good before we leave site.
Walk-through with the lead installer. You get the guarantee paperwork the same day and a follow-up call after the first heating month.
A few representative jobs from our recent work in and around Romsey.
Underfloor insulation between joists on the ground floor and a full PIR rafter-line system in the new loft space. Pre-empted the building-control thermal requirements and let the homeowner skip retrofit corrections later.
Underfloor and skirting insulation on a single-storey park home that had been close to uninhabitable in winter. Used moisture-tolerant boards beneath the floor and breathable skirting infill. Owner reported the heating coming on half as often.
1960s cavity-wall property with original mineral fibre fill that had slumped on the gable. We extracted the failed material, refilled with bonded bead, and topped the loft from 100 mm to 300 mm. Owner reported the upstairs bedrooms holding heat through the night for the first time in a decade.
Insulation done badly is worse than no insulation. These are the issues we're called out to remediate most often in Romsey.
Every installer working in Romsey holds the relevant industry accreditations (CIGA, NIA or BBA-equivalent depending on the system). Every cavity-wall install carries a 25-year guarantee, which only certified installers can issue.
Not when the property is suitable and the right material is used. The risk comes from blowing the wrong fill into an unsuitable property — typically a high-exposure or already-damp wall. Our survey rules those out before we quote, and we will turn down jobs we don't believe are right.
Government schemes such as ECO4 and GBIS are available in Romsey for qualifying households. Eligibility depends on income, benefits status and the EPC band of the property. Your surveyor will tell you in plain English whether you'll qualify and walk you through the paperwork if so.
All cavity-wall installs in Romsey come with the independent CIGA 25-year guarantee, which is transferable if you sell the property. Loft and underfloor installs carry our own 10-year workmanship guarantee on top of the manufacturer warranty.
Yes. We regularly survey listed buildings and properties in conservation areas around Romsey. The specification almost always uses breathable internal wall systems rather than cavity or external fill, and we'll handle the consents conversation with your local planning office if needed.
Someone over 18 needs to be on site at the start of the day to grant access and at the end for sign-off. You don't need to be present during the install itself — most cavity work happens externally and most loft work is contained to the loft space.
