uPVC or Aluminium: Which one fits your home?

Here's what you need to know before choosing:

The breakdown:
1. uPVC – A reliable choice with a lifespan of 20-30 years, great for smaller windows like kitchen windows or bay window replacements
2. Aluminium – The modern luxury option, ideal for bi-fold doors, lanterns, and large glazing
3. Flush or Chamfered – Aluminium comes in flush (hidden frames) or the classic chamfered look, giving you options to suit your style
4. Colour choices – Both uPVC and aluminium come in a wide range of colours to match your home

So whether you're after something practical or a high-end statement, there's an option to suit your project and budget.

Not sure which is right for you? That's exactly what we're here for.

Avoid These Common Kitchen Renovation Mistakes

Planning a kitchen renovation? Here are the biggest mistakes homeowners make and how to avoid them:

The biggest mistakes:
1. Underestimating the budget – Always plan for the unexpected, not just the ideal scenario
2. Hiring the cheapest builder – Cheap now often means costly problems later
3. Rushing the layout and storage – Getting this right from the start saves you stress (and money) down the line

A great kitchen renovation isn't just about how it looks — it's about getting the planning right from day one.

At J M A Group, we help you avoid these pitfalls with proper planning, honest budgeting, and a team that gets it right the first time.

Site Visit: Rear Extension in Progress

Take a look at what's happening on site as we extend this home 4 metres to the rear and completely transform the layout.

What's happening on site:
a. Rear and side walls coming out, with a steel beam going in
b. Lean-to pitch roof with interlocking tiles, set on a raft foundation
c. New outdoor patio being created, with steps leading down
d. Sliding door on one side and a new window on the other
e. 3 skylights being added to bring in natural light
f. Concrete slab flooring with underfloor heating throughout
g. Kitchen being ripped out and rebuilt as part of the new extension
h. New WC being added, partitioned off from part of the original kitchen space
i. The whole space opened up to create a seamless flow from the existing home into the new extension

This project is all about creating a bigger, brighter, more functional home with a new kitchen, extra outdoor space, and a layout that just makes sense.

From design to completion, J M A Group manages every detail.

When a "cheap" builder costs you £40,000 more than you bargained for

This customer paid £50,000 for a 16.5 sqm side extension — and was left with bent walls, mismatched blockwork, and a builder who never finished the job.

At J M A Group, we're now stepping in to put things right.

What we're doing to fix it:
a. Tearing down the poor-quality work and rebuilding from the ground up
b. Checking the ground works and confirming everything with the local council
c. Installing 3 new windows and a doorway, positioned properly this time
d. Adding a lean-to pitch roof and a new internal door
e. Boarding, skimming, and insulating the extension to the standard it should've been done at from the start
f. Rebuilding the ground works properly, start to finish

If you've been let down by a cowboy builder, or just want the job done properly the first time, message J M A Group today.

UPVC or Aluminium — which one's right for your home?

Both have their place, but here's the difference:

The breakdown:

a. UPVC – A cost-effective option, made from plastic, with a lifespan of 20-30 years. Great if you want quality without the higher price tag.
b. Aluminium – The higher-end, luxury choice. Stronger in strength and perfect if you're after large glass panes and a sleek, modern finish.

So if you're working to a budget, UPVC is a solid choice. But if you want that premium look and feel, aluminium is the way to go.

Not sure which is right for your project? That's exactly what we're here for.
