When it comes to retrofit projects, insulation and airtightness go hand in hand.

There is no point upgrading insulation if warm air is still leaking out through gaps, cracks and poorly sealed junctions.

A well-designed retrofit should do both, improve insulation to slow heat loss, and improve airtightness to control unwanted draughts and energy waste.

Why does that matter?

Because good insulation and airtightness can help

* reduce heat loss
* improve comfort
* cut draughts
* lower energy bills
* support better long-term building performance

The key is getting the balance right.

Retrofit is not just about adding more insulation. It is about understanding how the whole building works together walls, floors, roof, junctions, ventilation and moisture movement.

At Total Precision Developments, we look at the full picture to make sure retrofit work performs properly, not just on paper, but in real life.

Extending properties & Creating space safely its what we do.

To open up this property and allow for the extension, to another of our deep retrofit projects we installed structural steel beams to support the new layout.
This is one of the most important ,and potentially dangerous stages of any build.
It must be carried out by experienced professionals with the right planning and support in place. Especially now with architects and clients wanting big open spaces for windows, doors etc as you can see below not much was left of the corner of the house to get the steels in, yet in they went and the house is now more structurally sound than ever.
Once complete, the transformation is clear larger spaces, better flow, and a completely different feel to the home.
Another step in delivering a high-quality renovation.

PIR insulation or wood fibre insulation, which is better?

The honest answer is, it depends on the building.

PIR is a great option where you need strong thermal performance with a slimmer build-up. Typical PIR products are around 0.021–0.022 W/mK, so they can help achieve target U-values without taking up too much space.

Wood fibre insulation is a strong choice where breathability, moisture management and summer comfort matter more. Typical wood fibre products are around 0.043 W/mK, so they usually need more thickness, but they can help with moisture buffering and overheating performance in the right build-up.

At Total Precision Developments, we look at the whole picture:

* the type of property
* how the wall or roof needs to perform
* breathability and moisture movement
* space available
* and the overall goals for the project

There’s no one-size-fits-all answer. The right insulation is the one that works best for your property and the way it’s built.

📐✨ Smart retrofit upgrade!

We kicked out the roof to cover new external wall insulation (EWI) all the way up to the wall plate 👊. Then we:
🪵 Packed the roof with insulation
🌱 Added rigid wood fibre boards (natural + breathable)
🎨 Finished with lime render for a timeless look
💧 Installed sleek Lindab guttering + a rainwater harvesting fitting — so every drop of rain can be put to good use!

This means:
✔️ No cold bridging
✔️ Walls + roof fully protected
✔️ A breathable, long-lasting envelope
✔️ Rainwater ready for reuse 🌍

Retrofit done the right way = efficiency + durability + beauty.

Looking to invest in sustainable housing?

Internal Wall Insulation (IWI) is a key component for energy-efficient properties.

Our IWI system includes airtight and vapour control layers to regulate humidity, meeting PassivHaus standards and pushing toward zero-carbon targets.

By improving thermal performance without altering a building’s external appearance, IWI significantly boosts property value and long-term energy savings—an attractive proposition for future buyers.

Here at one of our deep retro projects in Liverpool, the architect specified a Limecrete slab.
Our team did a great job installing the slab with the team at Ty- Mawr lime providing a great service and product.
After we let the slab properly dry out, our tiler finished off the conservatory room extension with a beautiful Lime stone tile.

The architect had opted for the limecrete as it is a breathable, flexible alternative to concrete.

Limecrete is a little harder to work with however we are happy with the outcome and think the tiles are a stunning feature to this conservatory.

Feel free to get in touch if you have a retrofit project you want a reliable builder for.

Another heat pump installation completed at one of our deep retrofit projects.

Installing a heat pump in a property over 100 years old is a big ask.
However as you can see we also carried out various insulation & airtight works along with intello membranes.

After this we installed the underfloor heating system on the ground floor. With new radiators installed upstairs so the customer could access the grants available.

We now have a very warm property in December with very happy clients.

Steel beams installation at one of our Retrofit projects.

We have removed the window, back door, and part of the wall to open the area up to let in more natural light.

Inside the property we have installed a few more steel beams, in which one will be exposed.

Great work from all the team.

This is one of our current projects, A Deep Retro Fit, Passive house build.

We went back to bare brick, on a double fronted Victorian house.

The end goal for this project is to be a zero carbon build. We think this is the first for the Liverpool region.

We have also insulated the external walls with rigid wood fibre insulation. Soon to be rendered using a Lime render, this would be to the rear of the property.

We will be posting our progress throughout the project.
