A wood pergolas from Forever Redwood can provide a welcome shade zone, especially for homes that have a lot of sunlight in their area and not very much in the way of trees or natural shading. However, a pergolas project is not as simple as just choose a spot and start building. There are factors that can seriously affect the structure and the materials used. These include everything from the ground condition to local regulations.
Permissions and Allowances
For most neighborhoods a building permit and possibly a homeowner’s association approval will be necessary before any construction can get started. If you don’t have these in place the city or local HOA could force the homeowner to rip down and remove the pergolas built, usually after the job is complete and the money spent. It can be extremely frustrating experience, but unfortunately the requirement is legal. So avoid the headache by making sure all the permissions are taken care of.
Regions that see regular snow and freezing can end up having frost in the ground. If the pergolas load-bearing beams are not deep enough, the annual frost can push the beams upward out of the ground. That in turn will warp and eventually ruin the pergolas. The trick is to sink the beams deep enough below the frost level so that the beams are unaffected. That means more material and knowing the ground condition first.
Watch Out for Utility Lines
It can be common for utilities to have run gas or other lines underneath the ground about a foot or two down. A deeply sunk beam can require a hole that could uncover a utility line. Check with the local utilities first. They will come out and mark the line locations existing in a backyard, saving a very bad and potential harmful mistake from happening when digging.
Don’t Forget Exposure Protection
While made of pressurized wood, your pergolas will still need regular treatment with sealants and wood protectors. Make sure to apply these regularly to avoid dry rot and beam deterioration.
