In Lancaster the job is reviewed by the Building Permits & Inspections, Development Services, and we file and follow the permit through that office ourselves. Our permit guide lists the office for every city we have checked.

How do side gates affect work on older Lancaster lots?
On older Lancaster lots, big shade trees, narrow side gates and aging utility lines are common. Crew access and the path of the old lines get checked at the first visit, because they decide how a project is built more than any style choice does. A patio cover has to be carried or craned past those gates and trees. Where Ten Mile Creek and its tributaries run, native pecan, cedar elm and oak cover is likely, and an older oak is an asset whose root zone is marked before digging.
What does blackland clay mean for a Lancaster slab?
Lancaster’s newer neighborhoods have spread across former blackland farmland along the I-35E and I-20 corridor. Clay of that kind swells when wet and shrinks when dry, so a slab or footing needs to be designed for movement, with drainage kept away from the edges. It is one reason we look at where roof water runs before choosing a structure, and why the footing is not a place for shortcuts or guesses.
Are Lancaster’s mid-century houses ready for new windows?
Lancaster is a historic town founded in 1852, and its population more than doubled between 1930 and 1960 as it became a Dallas bedroom suburb. Houses from that growth are old enough that windows, doors and siding may all be original. Fix the openings first, then build outside. The city’s Building Permits & Inspections office decides what a job needs, so ask them before work begins, because the answer is theirs to give.

Ten Mile Creek and its tributaries run through the city, and areas near the creeks keep native pecan, cedar elm, and oak cover. Where an older oak survives on a lot, it is an asset: its root zone is marked before any digging, and its shade goes into the layout.

“American Eagle Builders are very professional and very tidy. They installed 19 windows and 2 patio doors over the course of two days and it was a very pain free experience. These energy efficient windows and doors are already starting to show a retun on investment with our utility bill savings. We've used 100Kw less electricity this week than the previous two weeks before installation and it's actually 10° hotter this week! These windows and doors are the best investment we have made for our home to date and they also give the house more curb appeal.”

“I had a patio cover installed. They first said the work would begin about six weeks out but to my surprise it began three weeks out. Jim was my installer and he went above and beyond to ensure I had a strong and properly supported patio cover built. Very pleased with the result and received a very favorable and fair price.”
