What makes a kitchen remodeling job less expensive?

in general, the appliances are not the big cost, but rather the counters and customized cabenits account for a high cost percentage in the new kitchen.  Expense for new ranges, ovens and other apopliances will of course come into play as well.

Where is the best place to install an oven?

Like most things about your updated kitchen, it will depend on how you and your family use the appliance.  From a safety and accessibility standpoint, the range and oven is high enough above the floor to avoid fires.  Consult with your designer for the best place to locate it.

Is pressure washing harmful to your home's siding?

Yes, pressure washing has the ability to damage vinyl or wood siding if done incorrectly or with too much pressure and force. It is also easy to break a window if the pressure is too high.

What are the benefits of seamless gutters?

seamless gutters have less joints, they don’t accumulate as much debris as sectional gutters do.  Small animals and rodents tend to favor others gutters so Sweemless wins there too.
