What actually makes a composite door good
A good composite door is defined by three things: a stable, dense core (timber or engineered timber), a UV-stable GRP skin, and a 3-star locking cylinder. Everything else is preference.
The brands we install and why
We install Solidor, Endurance, Hallmark, DoorCo and Distinction. Each brand has genuine strengths — see our brand pages for direct comparisons.
What to avoid
Avoid foam-cored budget imports, 2-star cylinders, and any door quoted without a written 10-year guarantee.
