Outdoor cleaning and maintenance specialists PBSR CO say minor exterior upgrades can significantly increase a property’s value by improving its kerb appeal, often for just a few hundred pounds. Gutter cleaning typically costs between £100 and £200, while repainting the front door can be done for £100 to £250. Driveway cleaning comes in at £150 to £350, and restoring a patio costs between £350 and £500. Render cleaning costs £300 to £800, while painting or staining fencing is priced between £200 and £500. Mr Essex recommends avoiding neon, purple or highly personalised colours that may signal redecoration costs to buyers.
