Integrated insulation, ventilation and restoration specialists for period and listed properties​

All-season comfort for your period home

What if your period home stayed warmer in winter, cooler in summer, and free from damp and mould? We help improve comfort, air quality and energy efficiency while protecting the historic character of your property.

Period and listed properties often suffer from:

Often, these are more than simply old house quirks; they could be signs your home is losing heat and not breathing as it should.

Comfort and preservation must work together

In period and listed homes, insulation and ventilation shouldn’t be treated separately. Insulation keeps warmth in during winter and reduces heat loss, thereby saving energy. Ventilation can remove excess moisture, stabilise humidity and prevent overheating. Working together, they:

FAQs

What is integrated insulation and how does it differ from standard insulation?

Integrated insulation combines insulation and ventilation into a single, comprehensive solution rather than treating them as separate problems. Our approach aims to address the whole building’s health – ensuring your home stays warm, dry and properly ventilated without creating damp or condensation issues that standard insulation can sometimes cause.

Can integrated insulation be installed in listed buildings and period properties?

Yes. We specialise in making period homes warmer while preserving their historic character. The solutions – including secondary glazing, draught proofing, natural fibre room-in-roof insulation, and heritage shutters – are fully compatible with listed buildings and conservation area properties, meeting planning and heritage requirements.

What insulation services does Mitchell & Dickinson offer?

Our integrated insulation services include full insulation, ceiling and loft insulation, underfloor insulation, bespoke secondary glazing (including vacuum glazing), UV protection glazing, draught proofing, window and door restoration, heritage shutters, and ventilation advice. We also offer consultancy and ongoing service visits

What problems can integrated insulation solve in my home?

Integrated insulation can address overheating in summer (particularly in loft spaces), cold and draughty conditions in winter, condensation on windows and walls, damp patches, mould, peeling paint, and rotting window frames – all common issues in period and older properties.

How does Mitchell & Dickinson assess what insulation my property needs?

Every project begins with an expert survey of your property. Our specialists assess your home’s specific heat loss, ventilation, and moisture issues before recommending a tailored combination of insulation and ventilation solutions – rather than a one-size-fits-all approach.

Will integrated insulation reduce my energy bills and carbon footprint?

Yes. Properly integrated insulation significantly reduces heat loss, lowering the energy needed to heat your home. This leads to reduced energy bills and a lower CO2 output. We are Carbon Savvy certified and specialise in improving the energy efficiency of older and period homes

Does secondary glazing also provide soundproofing benefits?

Yes. Secondary glazing can improve sound insulation, particularly when designed with acoustic performance in mind. While thermally efficient secondary glazing also reduces noise, the level of soundproofing depends on factors such as the building’s construction, its surroundings and the glazing specification.

Systems with a larger air gap or vacuum glazing generally offer the best acoustic performance, making them well suited to properties in busy urban areas, near roads, or in listed buildings where replacing original windows is not permitted.

As noise is perceived differently by each individual, it’s important to discuss your specific requirements with our surveyor if soundproofing is a priority.
