Keep the tree or no? Building a house and my construction Company said they would take the tree down and plant a better one

Looks like a pear, apple, plum or a cherry, not well maintained, 10-15 years old. Probably an apple or pear based on the flowers? It also looks like it was maintained at one point, you can see the sub-canopy which was probably being managed as the main canopy out of the main fork, and then you can see how it got super leggy and out of control from that point, like no one did any maintenance or management to the tree for a while (3-5 years).

Kind of depends what you want. Fruit trees are great but do require work, especially in terms of branch maintenance. You can't just let them go or they'll tear themselves apart. So every year you would be doing branch management, otherwise it will split, good chance of getting diseased, produce less fruit, produce fruit in place that you cant get to or are a pain in the ass to get to, and otherwise looking like crap. Domesticated fruit trees have evolved under human management and require regular maintenance otherwise they generally don't do as well. They don't self-limb effectively. Then there is the annual fruit harvest. You may need to use a pesticide depending on where you live to get fruit if you have a significant pest load (depending on the species). If this wasn't a planted variety, its fruit might be of questionable quality, but you can't really know that till the fall (earlier depending on the species/ variety).

The easiest answer: Hire a professional tree trimmer to do a skeleton prune and take this raggedy boi way back, then put off the decision till next year. That will get the branches out of the way for the construction crew and you can have them ID the tree and make sure they leave some flowering branches so you get some fruit. Put the decision off until you get some fruit; figure out what kind of tree it is (you really can't tell as many of this species group apart until fruiting), and go from there. Regardless, a hard trim is necessary on that tree, and you don't know if its worth keeping until you get to try some fruit.

Second piece of advice, don't worry at all about pulling the tree if you end up going that way. There are some ridiculous poets in the comments here who obviously have no conception of where food comes from or what nature is and represents. Unless you live in Kazakhstan, this is a non-native species, and you should be thinking about it as it its a wrench, or hammer, or any other tool. Domesticated fruit trees are a tool that humans intercepted their evolutionary paths and made them into food producing machines. They don't exist in nature. If the tool isn't doing what you need it to do, you should feel no obligation to continue to use it if it isn't working. Trees and plants die CONSTANTLY in nature. Don't worry about pulling it what-so-ever. If you decide you don't want the work of maintaining a fruit tree (probably 1, 3-6 hour day in the spring, and 1, 3-6 hour day in the fall for maintenance), consider putting in a native tree that's ecologically appropriate for wherever you live. Native species (and this isn't one of them) are struggling everywhere. They need your help, and can represent a much easier to manage (you don't have to do anything) option to a fruit tree.

Details are blurry in the photo, but it looks like it may be a Bradford Pear. If that is a Bradford Pear, you should have it removed.

From an ecological standpoint, they are highly invasive trees that can and do escape into the wild. If they aren't native to your area (and most places they are grown are not their native area), they out compete native trees and shrubs in the wild. In many places there are native tree options that out perform and (this is obviously just an opinion) look nicer, so you may want to research those options.

From an economic standpoint, Bradford Pears are poorly suited to locations that may experience periodic high winds or where there's any chance of heavy snow or ice in the winter. These trees grow quickly, but their wood is weak. The branches break off very easily, and the trees can even split in half. Giant branches can damage your property such as homes, fences, and vehicles. They can fall on people and pets. As the trees get older and more gangly, the chances of dropping limbs and branches are greater.

From a personal standpoint, the flowers smell gross and make a big mess when they are done blooming.

Of course, if it's not a Bradford Pear (and like I said I can't confirm with certainty based on this photo), then you can ignore my advice and rambling.

I would never take the builders/construction company's opinion on a tree. Get a second opinion if you can't decide for yourself. A better tree is going to take a long time to mature. Also, construction could lead to root damage and cause the tree to go into decline or lose limbs.

Better how? What's wrong with that one?

What kind of tree is that, some sort of Pear Tree? Bradford Pears are invasive to the US and very prone to falling over in high winds as they get older. Call an arborist and get their opinion if you want to keep the tree.

Keep

I think the construction company is just being lazy and doesn't want to work around the tree but if it's a Bradford Pear, they'd be doing you a favor. If it's on the south side of the house insist on the replacement being something sturdy and deciduous so you get shade in the summer and sun in the winter. Cherry bark and Scarlet Oaks are great. You have some leaf pickup every year, but as hot as the summers have been lately, you'll save a fortune on electric if it shades your house.

If you want it as an evergreen green screen, get a Southern Magnolia.

I'd keep it, and have it trimmed a little. A good arborist crew can trim a tree so that maintains its shape and is healthier (less prone to lose limbs in high winds). It's beautiful as it is though.

It is a living breathing being, vibrant and flowering, supporting a micro-ecosystem of mosses and lichens, not to mention all the insects and worms not visible, not a pair of old shoes.

Yes, like all living beings it will die, and sooner than you could wish. That's part of it. Deal with that as and when, and then plant something in its footprint. Or even better yet, plant something on the edge of its shadow now, ready to take its place when it does get ready to fall over.

It's not too old. Keep it!

It looks beautiful! Keep it!
