The 8 Factors That Determine Pergola Prices
A pergola cannot be priced from a ready-made list, because two installations of the same square metre area can cost noticeably different amounts once profile section and site access are taken into account. This article explains the eight factors so you can judge a quote yourself.
Why Is There No Ready Price List?
Pergola and glass systems are made to measure. Two installations of the same area can cost noticeably different amounts because of the system chosen, the profile section and access. This article lists the items that set the price, so you can read a quotation yourself.
1. Choice of System
The largest difference comes from here. The bioclimatic pergola, the motorised pergola awning and the Rolling Roof are separate products. Which is more economical is not a general rule; it varies with dimensions, model and equipment.
2. Dimensions and Span
Feasible dimensions are confirmed from your measurements and the structural design. As the span grows, the profile section and the supporting structure are strengthened; the unit cost does not rise linearly.
3. Roof Cover or Louvres
On a motorised pergola awning the roof is a three-layer waterproof PVC blackout cover; the model of the cover used is stated separately in the quotation. On a bioclimatic pergola the louvres and mechanism, and on a Rolling Roof the panels and model, are separate items.
4. Motor and Controls
The motor and controls are chosen for the size of the system and how often it is used; the selected model is stated in the quotation.
5. Sensors and Automation
Rain, wind and sun sensors and a timer can be added. Each is a separate item.
6. Lighting and Colour
LED lighting recessed in the profile is planned at the production stage and is a separate item. Profile colour and finish are stated in the quotation.
7. The Sides
Sliding, folding or guillotine glass and zip screens are separate products. How many sides are enclosed also affects the cost.
8. Installation Conditions
The floor and façade, installation height, the need for a crane and access change the labour involved; we assess these from your measurements and photos, and on a video consultation where needed.
How Should the Warranty Appear in a Quotation?
Warranty scope and periods are stated per product and component in the written quotation and the warranty document. Ask for the roof cover, motor and maintenance conditions to be written separately; a general "guaranteed" is not enough.
Questions to Ask
- Which model and which roof cover will be used?
- Which motor and control model?
- Have wind and snow loads been calculated for this project?
- Which condition does the warranty document state for which component?
- Are installation and transport included in the price?
Conclusion
The way to compare two quotations is to look at the items, not the total. For an itemised quotation, use the form on the contact page.
