Loft insulation installation

Professional loft insulation installation in Sussex

Improve comfort and reduce unnecessary heat loss with insulation professionally installed for your home.

What good loft insulation does for your home

Loft insulation is one of the most practical improvements in most Sussex homes — provided it is the right specification, correctly fitted and not compressed.

Why it matters

Improved thermal efficiency

Insulation fitted to a suitable depth helps reduce heat loss through the roof space.

A more comfortable home

Rooms below the loft feel steadier, with fewer cold spots in winter.

Professional coverage

Consistent coverage across and between joists, worked carefully around obstructions.

Installation tailored to the property

The specification follows the loft’s construction, access and ventilation.

From survey to clean-up

Every installation follows the same clear sequence, so you know exactly what is happening in your loft.

What the service includes

No two lofts are the same

Loft construction, ventilation, access and existing insulation vary considerably between properties. A Victorian roof with rafters and a small hatch behaves very differently from a modern trussed loft.

Older properties: irregular joist spacing, restricted access and existing material of unknown age
Newer properties: trussed roofs, tighter spaces and easier consistent coverage
Ventilation is considered so eaves are not blocked
Recommendations are tailored rather than one-size-fits-all

Planning loft boarding or storage?

Insulation should be considered alongside any planned loft boarding or storage improvement. Boarding fixed straight onto joists can squash insulation and reduce its effectiveness, so it is worth deciding on both at the same time.

Insulation and boarding work best together

If storage space matters to you, we will explain how the insulation depth and any raised boarding system need to work alongside each other, and prepare the loft accordingly.

Assess depth

Measure existing insulation and available height.

Agree the plan

Decide insulation depth alongside boarding plans.

Prepare the loft

Insulation fitted so it is not compressed later.

Loft insulation questions

How much loft insulation does my property need?

It depends on what is already there, the construction of the loft and how the space is used. We measure the existing depth and condition during the survey and explain what we would recommend for your property.

Can new insulation be installed over existing insulation?

Often yes, where the existing material is dry, clean and in reasonable condition. Where it is damp, contaminated or badly deteriorated, removal first is the sensible option.

Can I still board my loft?

Yes, but the boarding and insulation need to be planned together so the insulation is not compressed. We will explain the practical options for your loft.

How long does installation take?

Many domestic lofts are completed within a day. Larger, awkward or restricted-access lofts can take longer, and we confirm expected timings after the survey.

Do you remove the old insulation first?

Only where it is necessary. If the existing material is unsuitable, damp or contaminated we will recommend removal, using our specialist vacuum equipment.

Will you survey the loft before quoting?

Yes. We do not quote blind. The free survey lets us see the actual condition of the loft so the recommendation and price are realistic.
