What to check on a Northamptonshire quote
- FENSA or CERTASS registration number, verified independently, since you may need the certificate when you sell.
- Scaffolding shown as included or separately priced, particularly on two-storey and bay work.
- Making good defined: plaster repair, architraves and external pointing.
- Consent position confirmed in writing if the property is in a conservation area or listed.
- Guarantee length with named insurance backing, not just a promise.
How to get a fair Northamptonshire price
Three quotes for the same written specification, all from firms registered to work in your postcode, is the reliable method. Ask each installer for the same make and model of frame and glass, the same hardware grade and the same scope for making good, otherwise the totals you compare are not comparable at all. Take the highest and lowest out of the decision and compare the middle quote against both on scope rather than on headline price.
