Glendora is built on the alluvial fan of the San Gabriel Mountains. The ground is coarse gravel and cobble washed out of the canyons, and it drains and carries a slab far better than the valley floor.
That is good news for a driveway and bad news for a shovel. A fan like this is stable under load because water goes through it rather than into it, so the settling that wrecks slabs on clay is rare here. The cost is in the digging. A trench for a footing in north Glendora hits fist-sized stone within the first foot, and a compactor bounces on cobble that a finer base would take. North of Sierra Madre Avenue the lots climb too, so the same yard often needs a wall before it takes a patio.
So the base is sized to the ground rather than to a rulebook. Where the cut exposes clean gravel we compact it and pour straight on it. Where it is mixed with fines we lay 4 inches of Class 2 base and plate it in two passes. Every slab is jointed on a grid that keeps each panel square, and a hillside wall is footed into undisturbed fan material with drain rock and a perforated pipe behind the stem, because the water that keeps this ground stable still has to get past the wall.
Glendora lots are old enough to be on their second slab. Most of the work here replaces a 1950s driveway heaved by a parkway tree, or adds a patio and a wall to a foothill yard that was never flat to begin with.
Most Glendora driveways south of the 210 are the 1950s originals, a single car wide and cracked through. We cut and haul the old slab, widen the approach under a Public Works permit where it meets the curb, and pour 4 inches on compacted base with steel through it.
A patio on a Glendora lot usually replaces the builder's 8 foot slab at the back door. We extend it on the gravel the fan already provides, joint it every 10 feet and dowel it into the old slab, so the two pieces move together through the summer heat instead of opening a step.
Stamped concrete in Glendora is asked for in the foothill neighborhoods, where a poured patio sits beside natural stone. We cast a flagstone or ashlar pattern into a 4 inch slab, color it to sit with the rock around it, and seal it in 2 coats so the pattern holds its edge.
Glendora sidewalks on the older streets have been lifted by parkway trees for decades. The walk is in the city right-of-way, so we take out the encroachment permit, trim the roots back behind a barrier and pour new panels doweled to the old, so nobody trips on the joint.
Garage floors in the Glendora tracts are 60 years old and often cracked and dusting. Where the slab is sound we grind and coat it. Where it has heaved we break it out, recompact the gravel underneath and pour a new 4 inch floor over a vapor barrier so the coating stays down.
Decorative concrete in Glendora most often means a light integral color and a salt or broom finish, because a dark slab in a San Gabriel Valley back yard is too hot to stand on by mid afternoon from June to September. Exposed aggregate suits the older houses near the Village.
Retaining walls are the foothill job in Glendora. A lot north of Sierra Madre Avenue is rarely flat, and a wall that turns a slope into a usable yard is footed into undisturbed fan material, drained with rock and a perforated pipe, and engineered where it passes 4 feet in height.
Interior floors in Glendora come with the garage conversions and the backyard units the state now allows on a single lot. We pour over a vapor barrier, trowel the slab flat enough for tile, and cut the joints on a grid that suits the room rather than the crew.
Our yard in Fontana is 22 miles east of Glendora, and the 210 runs door to door, so a crew is on site in well under an hour and we usually book two Glendora jobs in one week. Plans go to the City of Glendora Building and Safety Division. Anything touching the sidewalk or the curb also needs an encroachment permit from Public Works, because the parkway belongs to the city even where you mow it. We file both and meet the inspector.
The town has three bands of housing and each asks for something different. The blocks around the Village and Glendora Avenue are 1920s to 1940s houses on deep lots with mature trees, where a walk has been lifted by roots and the new one goes over a root barrier. South of the 210 the 1950s and 1960s tracts still have their original driveways, cracked and too narrow for two cars, so the job is a tear-out and a wider pour. North of Sierra Madre Avenue the lots climb into the foothills.
Up there the work is walls, steps and pads cut into a slope. The Colby Fire in 2014 burned the hills above these streets, and a burned slope sheds water and stone for years afterward, which is why a foothill wall here is drained and footed rather than stacked. The season is set by heat more than rain. The San Gabriel Valley runs past 100 degrees in July and August, so summer pours start at 6 in the morning, and the winter rain in the Big Dalton Wash costs us a few days a year.
Four stages with one crew from the first visit to the sweep-up. The measure comes before the figure, and the figure is written on site, so the number you agree to at the start is the number at the end.
Andre Whitfield measures the area, checks the fall toward the street, probes for cobble where a footing will go and writes the figure there.
We file with the City of Glendora Building and Safety Division and, for any work at the curb, with Public Works. You attend neither.
The old slab is cut and hauled, roots are trimmed back behind a barrier, and the base is compacted to suit the gravel it sits on.
Most Glendora jobs take 2 to 3 days. Joints are cut the same day, you walk on the slab after 24 hours and park on it after 7 days.
Call or send the form and we will call you back within 1 business day to set a time. The measure and the written figure cost nothing, and a Glendora visit fits most weeks because the 210 does the driving.
Reviews
Reviews left on Google and Facebook by homeowners across the towns we cover from Fontana. Glendora is among them, and the driveways and walls behind the reviews are the ones described above.
“Our house south of Valley is one of the old steel-town builds and the driveway had never been replaced. They broke out 520 square feet, screened the cobble out of the base and poured 5 inches. Andre cut the joints himself before he left.”
“We are in one of the newer tracts up north and the builder patio was cracked across the middle in three years. Fontana Concrete Pro dug it out, put a proper base under it and poured 320 square feet with joints on a 10-foot grid. No cracks after two summers.”
“The slope at the back of our lot in Jurupa Hills was moving every winter and taking the fence with it. They poured a 40-foot wall on footings to 24 inches with drainage behind it. Two wet seasons on and there is not a crack in it anywhere.”
What people in Glendora ask before booking, covering what moves the estimate, which permits the city wants, how the foothill ground behaves and how long a driveway is out of use.
Area first, then what has to come out. A 1950s driveway south of the 210 is a tear-out before it is a pour, and the haul is part of the job. On a foothill lot the digging is slower, because a trench hits cobble in the first foot. Thickness, steel and finish move it after that. Every estimate is measured and written on site, so the figure comes off a tape measure and not a phone call.
Not for a patio or a path at grade in your own yard. Yes for a retaining wall over 4 feet, for a footing that carries a roof, and for anything at the sidewalk, curb or driveway approach, which sits in the public right-of-way. We apply to the City of Glendora Building and Safety Division and to Public Works for the encroachment permit, and we meet the inspector.
It settles far less here than in the valley, because the fan gravel under Glendora drains and carries load. What cracks a slab here is a tree. The parkway trees on the older streets push roots under a walk within a few years, so a new one is laid over a root barrier and jointed every 5 feet. Control joints cut on the day of the pour keep any crack in a straight line.
Our yard is in Fontana, 22 miles east, with the 210 running door to door. The drive is under an hour and it is not on your estimate, because we book Glendora jobs together and a crew is out here most weeks. You get the same call-back within 1 business day as a job on our own street, and the work carries a written workmanship guarantee against defects in how it was built.
About 10 days from the first cut. Tear-out and base take a day, the pour takes one more, and then the concrete needs 24 hours before you walk on it and 7 days before a car goes on it. A patio or a walk is quicker at both ends. In July and August we pour at first light, because a slab finished in 100 degree heat dries at the top before it sets underneath.
Yes. Azusa, San Dimas and Covina share a line with Glendora, and Charter Oak is the unincorporated pocket between Glendora and Covina, permitted by Los Angeles County rather than a city. All of them are on the same 210 run from Fontana, so a job on any of those streets is booked and run the same way as one in Glendora.
Glendora shares boundaries with Azusa, San Dimas and Covina, and we cover all of them along the same 210 run. If your street sits on a city line, the page for the town on the other side of it will fit your job just as well.
